It has a back ribbon, which makes it look slim and improves your figure. There is a black stain in one place, but it's on the back and towards the bottom, so I didn't mind it. Please refrain from purchasing if you are concerned. The size is listed as 36, but it was too big for me, who usually wears a size S, so it seems like it would fit someone who wears a size M. It has a very beautiful shape. You can wear it any time except for summer.
