The tag on the neck says LL, but personally, I felt it fit like an L, so I've selected L for the size. I bought this with the intention of using it, so I washed it once. I usually wear an LL size, but this one is a bit tight, so it runs small. There might be some discrepancies, but please refer to the measurements below as a guide (^ ^) ▪️Shoulder width: 37cm ▪️Body width: 45cm ▪️Sleeve length: 60cm ▪️Length: 60cm It's a simple design that middle and high school students can wear to school. I plan to ship via YuYu Mercari便, so I will fold and compress it to fit in a mailbox. Please understand.
