It's a white knit sweater. Silver glittery threads are woven in, which is most visible in the third photo, but it sparkles even more in person! It was in a lucky bag, but my arms are short (I'm 165cm tall) and I can't do the "sleeves that cover your hands" look, so I'm looking for someone who can wear it cutely! I'm not sure about the size, so I've written M. Even someone who is 165cm tall will have the sleeves reach their wrists!
