Gelato Pique Roomwear One-Piece Romper While it's not made of the fluffy material, wearing a cardigan or similar over it would, I think, enhance the look and make it even cuter! ♪ I bought it for around 7800 yen. I wore it once to a pajama party with friends, but haven't worn it since, and it's clean. The leg portion is like pants, so you don't have to worry about it riding up when you sleep, and it's easy to move around in. Thank you! ^ ^
