I purchased this dress for an upcoming prom. The dress fits very well. According to ellabride's sizing guidelines, I'm in between a size 12 and size 14. I bought the size 12, and it fits great, though it's a little snug in the breast/shoulder area. (I'm large-breasted and sometimes work out my shoulders/arms, so I'm larger in those areas. Clothing is often snug in the shoulders for me, so the dress's fit is typical for my body.)
