This is a baby wicker, onesie sold separately. you can use poiyomi but I prefer liltoon for a cleaner look on pc end. there are 4 physbones so it's easy quest compatibility. Just import the current poiyomi and use VCC (VRchat creator companion) import liltoon if you like ( https://booth.pm/ja/items/3087170 ) then the avatar. put in its parameters and menu manually and you can add gogo loco if u like. Don't know how? here! ( https://youtu.be/qOTV-g_EcXY?si=8ZeF6AOrkM6fXCBq ) sadly there are no textures to put on besides the main one. gotta ask someone to make one for you or make one yourself. HAVE FUN!

note: Baby wicker seems to not be sold anywhere anymore so sorry!
