Hmmmm, the first thing that comes to mind for me is me Peekabu hats. That's kinda their purpose imo haha. Pretty much to be a flag/beacon to other ABs and to rep a diaper design and company I like. I also have some shirts that are pretty clearly babyfur or diaperfur themed that I only really wear to furry conventions and other places I'll meet up with other babyfurs and diaperfurs, I never just wear them out and about
.
I actually have the hoodie and a t-shirt with this on it cause I like it so much
This is the shirt for the first in person Babyfur Con (BFC). It's super cute and done by the artist Marci McAdam who has a really adorable style and draws babyfurs really well.
This shirt is from Capcon and features the Crinklz tiger (which was also drawn by Marci McAdam). I didn't actually attend Capcon, I'd love to, but ordered the shirt from the con when I found out they were selling it.
Dracky is another artist that draws really cute babyfurs and diaperfurs and has an etsy that sells tons of awesome stuff. This shirt is from her store. This one is relatively subtle imo, at least compared to the other ones lol
I guess also my onesies would be a pretty clear indicator that I'm AB too, but someone would only see those if they looked in my closet or I'm wearing nothing but a onesie around them which means they'd probably be AB themself. I guess if someone were to happen to see the collar of the onsie under my shirt and recognize it, but once again, that'd probably mean they're AB themselves.
