Big Hips and Thighs
Your best bet is to find a dress that fits well at the bust and has a high waistline and a billowy skirt, like this David Meister Ombre' Silk Dress, $688 at Nordstrom. You'll look tiny because the size of your legs won't be an issue at all underneath all that fabric -- your overall size will appear to be the size you are on top. Avoid dresses that have a low waist or are fitted around the hips and thighs.
