Fit: I ordered S but I exchanged it with M because for S, it is tight around my hips but waist is perfect. For M, the waist is a bit big but it is more comfortable. My sizes are accurate so you can refer to my measurements and decide your fit accordingly. The product measurements they provided are accurate. Product Quality: good. Has a structure. Not thin per se but not for the material for humid summer I would say. Not transparent at all, don’t worry.
