I absolutely LOVE this dress. Bought it for an upcoming event and it is almost perfect. Many reviews stated that the dress ran small. I ignored the reviews and took my measurements and ordered a medium (that’s the range I fell into). I tried the dress on the same day it arrived and it’s too large. The top does not fit my frame at all. I’m 5’4”, 138lbs, B/C cup (smaller on top), and curvy on bottom. The top wouldn’t stay put and I could not fill this out even with inserts. I went ahead and ordered a small hoping this will work. The zipper is a bit sticky so I’m a tad nervous about sizing down. The dress is absolutely gorgeous. If you can get your sizing right it’s perfect. Definitely suited for larger cup sizes. Worth noting is that there is an attached bodysuit that snaps. That portion fit perfectly (medium) so I’m nervous about that sizing, as well.
