"Here, try these on first." She passes a bundle of clothing into the changing room.
"Black jeans and a tank top?" You look them over incredulously.
"What, don't like them?" She quirks her head at you, daring you to challenge her taste further.
"Um, they're nice, I'm sure they'd look good on you but like... are people gonna like, know I'm a girl in these? Like, I could've worn this before I came out."
She grins wolfishly, "Trust me, they'll know you're a girl."
"O-okay." Your doubt folds to her confidence. You nod, close the door and begin to change.
"What?!" The word falls out of your mouth when you check the mirror. The girl staring back at you is at once the most and least "you" thing you've ever seen. You run your hands over your waist. Over the curve your tank top makes plainly visible. "When did..."
"Clothes that fit are nice, aren't they?" Her voice comes smugly through the changing room door.
"I-I, um, I g-guess so." You can see yourself blush in the mirror as you stutter.
"Try jumping." You can hear her grin, which means she can definitely hear your blush.
"Like, just bounce a little, on the balls of your feet. Trust me, you'll enjoy it."
You follow her instructions, lifting your heels in a hop that doesn't fully leave the ground. "Ah!" You give a little yelp seeing your tits bounce. "Th-they can do that!?"
"Of course they can, they've probably been big enough for awhile, you've just never shown them off properly. Speaking of, open the door. I'm dying to see those on you."
