size slightly smaller than usual size.
Asian Sizes are so very different, it's almost like guessing. And I have not yet found a reliable scale, like there is for english vs german shoes for example. I usually wear a size L, I ordered a size 4XL, and it is quite tight. There was a very nice surprise when I opened my paket. There was this darling scrunchie inside. So even if it is difficult with the non-comparable sizes, I highly recommend this seller.
