♡Scenario: Their S/O wears their clothes (Suggested by @nightlady507)
Sans AUs x Reader
Undertale (Vanilla) 🍦
•he secretly finds it incredibly comforting that you smell like him, and that his hoodie now smells like you.
•while he may act nonchalant, seeing you in his blue jacket actually sends his soul into a bit of a flutter. just really gud at hiding it behind his grin.
•this is Classic, so expect immediate and terrible clothing puns
•he won’t even ask for it back, he’ll just use it as an excuse to avoid doing laundry for another week since “you’re already keeping it clean.”
•he loves when you wear it out cuz it gives him a quiet sense of pride that everyone knows you’re with him.
•You’re lounging on the couch, wearing his giant blue hoodie. Sans walks into the room with a ketchup bottle, as he stares at you and grins, a faint blue hue dusts his cheekbones. “y’know, if you wanted to be closer to me, you could’ve just asked for a hug. but hey, it looks better on you anyway.” He plops down next to you, pulling the hood over your eyes and chuckling as you bury your face in his shoulder.
Underswap (Blueberry) 🫐
•Blue’s eye sockets will literally turn into giant stars, for him ts is the highest form of flattery.
•he’ll aggressively compliment you. Telling you how magnificent and perfect you look in his battle body.
•Bro would immediately pull out his phone to take a million pictures to send to Papyrus (who will absolutely tease him later).
•Seeing you in his clothes will make him want to go out and buy you a matching set of your own “battle armor.”
•To Blue, wearing his battle body means you want to be a magnificent guardsman just like him.
•You walk into the kitchen wearing Blue’s blue bandana and his fit. Blue gasps when he sees you, his eye sockets turning into literal giant stars. “M-MAIDEN! YOU LOOK ABSOLUTELY MAGNIFICENT! THE ROYAL BLUE SUITS YOU PERFECTLY!” He rushes over, lifting you into a enthusiastic hug, entirely forgetting about the tacos on the stove. (it burnt af now)
Underfell (Red) 🍫
•Red’s entire skull will turn bright, glowing crimson.
•bro will look away immediately and try to act like he doesn’t care. (tsundere ahh)
•he’ll immediately try to cover up his embarrassment by acting annoyed, even though he’s secretly thrilled.
•He loves the visual reminder that you are his and only his.
•he’ll eventually grab you by the waist, pull you close, and complain that he’s cold now, just to share the jacket with you.
•You’re wearing his heavy black and red jacket, hands buried in the pockets. Red walks in and freezes, his face lighting up like a Christmas tree. “the hell do you think you’re doin’ in my gear, sweetheart? take it off,” he growls weakly. When you shrug and start to unzip it, he lunges forward, grabbing your hands. “tch—whatever, just…keep it on. it looks better on you anyway.”
Swapfell (Blackberry) 🍇
•He loves the look of his dark, elegant colors on you.
•Like Vanilla, he enjoys the fact that you smell like him, but he’d rather dust himself than admit it out loud.
•Bro will look at you, scoff, and tell you that you look ridiculous and sloppy in his attire.
•Inside, his soul is doing backflips.
•To hide his blushing, he would meticulously adjust the collar of his clothed, claiming he’s just “fixing your terrible presentation.”
•You’re working at a desk, wearing Blackberry’s high-collared purple capelet and sweater. He struts into the room, and crosses his arms, a purple blush creeping onto his purple cheekbones. “ARE THOSE MY CLOTHES? YOU LOOK ABSURD–THAT BELONGS TO A LORD, NOT A PEASANT.” He walks over, his gloved fingers gently but firmly turning your chin up. “BUT…I SUPPOSE I CAN OVERLOOK YOUR THIEVERY, FOR A PRICE.” He leans down and kisses you deeply. (sly mf)
Ink 🎨
•Ink will stare at you for a solid three minutes without blinking.
•Depending on his vial levels, he might genuinely forget that those are his clothes first.
•Once he finally realizes what’s happening, he’ll get incredibly excited and want to paint a portrait of you immediately.
•Seeing you comfortable in his things gives him a genuine spike of affection that doesn’t even require his vials to feel.
•His clothes are usually covered in paint, so expect him to apologize if you get dirty, but ofc he’ll think it looks cute on you.
•You’re wearing Ink’s giant, stained brown scarf wrapped three times around your neck, along with his oversized undershirt. Ink steps out of a puddle of ink, takes one look at you, and his eyes cycle through a dozen different shapes and colors. “Oh wow! You look…amazing love! Hold still, the lighting is perfect!” He frantically whips out a sketchbook and a paintbrush, sketching you with a massive, giddy smile. (CUTIE PIE I CAN’T)
Error 🧶
•error.exe has crashed
•while he hates being touched, you wearing his clothes is like a loophole he loves.
•he’ll mutter about how you’re getting your “weird anomaly germs” all over his favorite jacket, but he won’t make any move to take it back.
•like Blueberry, Error might even sew you a matching fit
•he might use his blue strings to gently tug you closer to him just so he can admire how you look in his fit.
•You walk into the anti void, wearing his signature black and blue hoodie. Error immediately glitches violently and crashed. Once he reboots, he glares at you, a heavy yellow blush on his cheekbones. “w-WhAt dO yOu tHiNk yOu’Re dOiNg?! yOu’Re gOnNa…mEsS uP tHe fAbRiC, yOu sTuPiD gLiTcH…” He turns away, but a blue string gently wraps around your waist, pulling you onto his beanbag chair next to him.
X-tale (Cross) ❌
•Cross is surprisingly soft and easily flustered. (CUTIE ISTG)
•Seeing you in his massive, monochrome fluffy jacket will turn his purple cheekbones completely bright violet.
•Cross has lost a lot in his life, so seeing his partner safe and wearing his clothes gives him a profound sense of comfort
•Chara will absolutely roast Cross for how whipped he looks, which only makes Cross blush harder.
•This guy will definitely pull you into a hug just so he can rest his face against the fluff on your shoulder.
•You’re sitting on the floor of your shared room, wearing Cross’s massive black-and-white jacket. Cross walks back from a quick scouting trip with a chocolate bar in hand and stops dead in his tracks, a purple blush spreading all the way to his pinpricks. “I…uh…you look really nice,” he mumbles, rubbing the back of his neck. He clears his throat, and walks over, sitting right behind you and wrapping his arms around your waist. “You…look warm,” he murmurs into your shoulder “Keep it on, please?”
Dream 💫
•Dream will practically glow with positive aura.
•He’ll shower you with compliments like Blueberry, except less aggressive.
•He views the act of sharing clothes as an incredibly intimate, so he’ll feel deeply touched.
•He will playfully treat you like royalty while you’re wearing his golden accents, bowing to you or kissing the back of your hand.
•Dream loves the idea of sharing everything with his partner, bro will happily let you keep whatever you want from his closet.
•You’ve draped Dream’s golden, star-clasped cape over your shoulders while reading a book. Dream walks into the room, and golden warmth immediately fills the air. His eyes soften into pools of pure light, as he walks over quietly, kneeling by your chair, he takes your hand, and kisses your knuckles. “My star…you look absolutely beautiful. If I didn’t know any better, I’d say you’re already my queen”
Nightmare 🌑
•Nightmare would be both smug and possessive once he sees you
•dude is hella possessive, seeing you covered his clothes signals to his entire gang that you are strictly off-limits.
•he tries to feed on negative emotions, but seeing you look so cozy in his sweaters actually brings him a quiet sense of contentment, which he will deny fiercely (tsundere 2.0)
•he’ll use his extra appendages to reel you into his lap, wrapping his dark tentacles around you like a blanket over his clothes.
•bro would smirk and comment on how his dark aesthetic perfectly fits you, treating it as a testament to his good taste.
•You’re wearing one of Nightmare’s regular sweaters. Then you feel a cold, slimy, yet gentle grip around your waist. A cyan eye glows in the dark as Nightmare pulls you flush against his chest. He chuckles, a dark, vibrating sound. “marking your territory love? or just desperate for my scent? either way…it’s a good look on you, don’t take it off.”
Dusttale (Dust) 🌪
•Dust is very attached to his hood, so if he lets you wear his hoodie, then it means he absolutely trusts you more than his own life.
•seeing you in his hoodie makes him feel like his safe space is now your safe space.
•he won’t say much, he’ll just stare at you with a ghostly purple blush, his mind racing with how lucky he is to have you. (bro is down BADD)
•he’ll use it as an excuse to drag you to bed for cuddles, claiming you stole his warmth so you have to replace it. (Red 2.0)
•his loves that your scent mixes in with his clothes (NOT IN A WEIRD WAY) he finds this incredibly comforting, often helping him quiet the manic voices in his head.
•You have Dust’s grey, dust-streaked hoodie zipped all the way up to your nose. Dust walks in, murmuring to his Papyrus, then goes completely silent when he sees you, his purple eye lights flicker. “Papyrus, shut up for a second,” he mutters, walking over to you. He grabs the strings of the hoodie, pulling you close to him “you’re crazy, ya know that? stealing a killer’s clothes, guess I gotta keep an eye on you now.”
Killer 🔪
•Killer will immediately start cackling.
•unlike Error, he has zero concept of personal space, bro will immediately throw his arms around you, and slide his hands into the pockets of the jacket.
•his shirt usually has a giant target on it, so bro would use that to his advantage to make cheesy pick-up lines about you ‘targeting his heart’
•thinks it’s both hilarious and badass, he’ll want to take you out to show the rest of the gang just to mess with them.
•he likes the domestic, normal feeling of a partner stealing his clothes.
•You’re walking through the castle hallways, wearing Killer’s target-printed shirt and jacket. Killer turns the corner and spots you, letting out a loud cackle “whoa, mama! didn’t know I hired a stunt double! you look way better in that than I do, babe.” He jogs over, throwing an arm heavily around your neck, dragging you into a messy side-hug. “c’mon, let’s go see if we can trick Nightmare into thinking you’re me.” (ye bruh ts ain’t working)
Horrortale (Axe) 🍴
•for a second, you might think he’s mad, but he’s actually just completely mesmerized.
•he’ll melt inside the moment he sees you snuggled up in his clothes
•bro would become incredibly gentle, handling you like a fragile glass doll so he doesn’t tear the clothes or hurt you.
•Axe is deeply insecure about his gruesome appearance, so seeing you willingly wear his blood-stained or worn-out clothes reassures him that you truly love him. (MY BABY 😭)
•he won’t say much, but he will walk over and sit down heavily next to you, just to bury his face right into your neck, breathing in your scent mixed with his coat. (again, not in a weird way)
•You are wearing Axe’s giant, heavily stained blue jacket. Axe trundles into the kitchen, and freezes when he spots you, his single red eye light dilates to the size of a saucer. He walks over silently, lifts you off your feet with one arm, and buries his face in your hair “…warm?” he rumbles out softly, you nod, and he lets out a deep, rattling purr, holding you tighter.
Epictale (Epic) 😎
•Epic will immediately react with dramatic anime-style poses. ( son 😭)
•he’ll yell out a catchphrase or act like you’ve ascended to a higher level of coolness.
•his purple trench coat is iconic, and he’ll love seeing you twirl around in it.
•he’d insist on turning it into a runway fashion show, putting his cool shades on your face to complete the look while playing hype music from his phone.
•behind the memes, Epic is a smooth talker, he’ll catch you by the waist, dropping the meme persona for a second, and tell you that you look genuinely beautiful (I swear guyz he’s just a silly nerd-)
•You’re wearing Epic’s long, purple and black trench coat, trailing it along the floor. Epic bursts through the door, and drops the cookie in his hand “BRUH! look at the drip! you look absolutely legendary!” He slides across the floor on his knees, stopping right in front of you. He takes off his purple sunglasses and slides them onto your nose. “yep, officially cooler than me. that’s it, we’re getting married, bruh.”
Fresh 🌈
•his 90s-active sunglasses will flash words like ‘CUTE’
•he doesn’t quite understand human romance conventions, but he finds it “totally radical.”
•be careful though cuz his clothes are blinding
•he’ll use his usual 90s slang to compliment you, calling you a “totally rad bae” while blushing a bright rainbow color.
•even though he’s technically a soul-less parasite, being around you when you look so comfortable in his gear gives him a fuzzy feeling he can’t quite explain.
•You’re wearing Fresh’s neon windbreaker jacket. Fresh skates into the room, doing a kickflip before stopping dead. His glasses that spelled ‘YOLO’ quickly changed to ‘CUTE’. “whoa there, babe! you are totally rocking the fresh style!” He skated over, booping your nose with his finger, and plops his colorful snapback hat onto your head sideways. “now we’re matchin’, totally choice.”
