This dress is extremely comfortable and easy to wear with a bra. the back is great and the length is perfect for me. it's flattering, but the pattern (being light in color across the middle) isn't particularly flattering on your waist. that being said though, the gathering in front is great for hiding bumps and whatnot (after 3 kids that's important to me). lightweight and great for summer. 5'8", 135lbs and the size s fit perfectly.
