The BT21 characters are cartoon avatars for our favourite septuplet from Seoul. Designed by BTS themselves, Koya the sleepy koala, RJ the epicurious alpaca, Shooky the anti-milk cookie, Mang the breakdancing shy pony, Chimmy the sweet puppy, Tata the shape-shifting alien, and Cooky the buff pink bunny have their own YouTube show (with 4.8m subscribers) and merchandise line (almost) as extensive as their idol dads. We love this shirt featuring their adorable faces in an almost Liberty-like print ($37-$41), sized up to 3XL.
