This is a really nice summer dress for those of us mid sized ladies. If you are bigger on top, size up one size. For reference, I am 5’9 1/2” & a 38DDD, and I wear a 13-16 jeans, depending on the material. The fit of the XL was fine in the waist, but the shoulders & bust were noticeably too tight, which made the shorter front of the dress hike up to try to accommodate.
