Looking for ABDL clothing links for big boys

Hiyya, I've been looking for some adult baby clothing for a friend of mine but most is really reall baby-ish in style (pastel colors & designs) .
What i was looking for is clothing for a different age category, say 7-9 ish with "cool" designs.. sort of a tough guy look but still cute ;-)
Anyone have tips ? Onesies/Rompers/etcetera, bear print would be nice since he is quite the cuddly guy
It seems there still is a bit of an open market for this..

Any advice and tips are greatly appreciated !

Off hand, there's a lot of adult Star Wars-themed clothing ATM which wouldn't look out of place on a 7-9-year-old. Including pyjamas.

You might try sites like Etsy and Ebay. Just type in adult baby and a lot of clothes pop up.
