If You Want to Cover Your Thighs
Look for an slightly flared, A-line dress. The fuller shape is fashionably retro, and the fit won't cling to (and emphasize) your curves like a pencil skirt would. The gentle pleats and waist-bow on this pick will also draw attention toward your centerand away from your hips.
