This gorgeous JSK from the Taobao brand Neverland (which I think has now changed its name to Soufflesong) was one of my favorite piece, but I never wear it much anymore since it's too big.
This is the size S, however it's very very stretchy so I think it could easily accomodate up to a M/L (my approximate measurements were bust 30-40 inches, waist 22-38, but it also has lacing on the back to make it smaller)
The bow on the back is detachable, and the straps are also adjustable. The dress is in great condition, the only flaw is that one of the buttons has been resewed on with gold thread. 
Breaks my heart to sell this, I hope it goes to someone who will love it! <3
