I am on the border of the small and medium sizes and opted for a small because I planned to wear this bodysuit as a single undergarment for a slinky dress and wanted everything to be held in place. Most unfortunately this did not work out as planned, as the bottom half was a bit too tight for comfort and the shape of my boobs just didn't stay put in the bodysuit how I envisioned.
That being said - it is so very cute and I am super sad it doesn't fit! Clearly well made and the color is beautiful. I've never really bought lingerie before so this was a great learning experience about what does and doesn't work for my body shape. I will definitely keep an eye out for other products (size medium!) in the future that might suit me better.
I'm pretty sure I have a friend who will fit into this (she's getting married soon) so I doubt this high-quality product will go to waste ;)
