Thinking a lot lately about the appeal of Littles / Middles who are, like, casually shameless about their diapers (or other general immaturity). By which I mean, e.g.,
Confidently wearing outfits that either have no hope of hiding their diapers or, better yet, are styled with flattering waistband peeks or bottom poof in mind. If they could get away with just a diaper and top when it's hot out, they wouldn't bother with anything else. At home, they probably don't.
Being completely unflustered by other people noticing their protection or that they need a change. ("Oops, be right back, I'm super soggy!", "Oh, sorry, do I smell...? I get kinda noseblind to it sometimes," etc.) Checking themselves in front of others without missing a beat.
Cheerfully indulging Little habits around Big friends or just in passing in public, and meeting any questions or stares with ready explanations. (Obviously, they're going to take their paci with them to class; it helps them concentrate if they start feeling anxious! Yeah, they needed braces pretty bad when they were younger because of it, but their dentist says it's not a big problem now...)
Flirting up a storm regardless of the state of their diapers. Worst case, they'll just use it as an excuse to suggest that, hey, maybe you wouldn't mind helping them get changed...? Somehow being able to make the other person blush while they're the one laid out on the changing table.
For the more online Little, having a social media footprint that's constantly oversharing, whether that means dumb throwaway posts about the state of their padding and latest brand or a whole TikTok channel full of "Get Changed With Me!" videos of them yapping while they clean up.
Never letting their lack of potty-training hold them back from doing anything else! They're going to captain their local sports team even if they're waddling off to the locker room afterwards, be the mentor and lead at work or in class even if their juniors will probably all be helping change them at some point, etc.
There are lots of potentially good flavors of this, too! Proudly Little social butterflies who will light up any room enthusing about their stuffed animals, would-be serious Middles who just aren't going to let you make them feel ashamed that they still poop their pants, etc. etc.
It's funny, because this is not my personal vibe at all, since getting to be shy and awkward and feeling "held back" are big parts of Middle-ness for me, so I suppose the appeal here is closer to "Little/Middle I would definitely have a crush on"...?
