Many reviews on here stating the dress is tight. I was nervous ordering the S because the M has sold out. Turns out it fits perfect. The dress is meant to hug every single curves on your body in a good way. It’s embellished so I feel my belly aren’t shown like it would with other tight dresses. Glad I ordered the S. It’s a gorgeous expensive looking and feel dress. For reference, I’m 5’1, 127lbs, 36-38C.
