Structure is a girl’s best friend. Flimsy, gauzy fabric and relaxed styling doesn’t flatter most shapes. Instead find a dress with sturdier fabric and plenty of internal structure. This navy dress above would work well on both athletic and curvier, hourglass bodies because of how the bodice is designed. Slimmer figures will look lovely (think Audrey Hepburn) and bustier pals will have the benefit of an accentuated waist to avoid making them look frumpy.
