Avoid anything that highlights your mid section, choose outfits that highlight your waistline but conceal your hips. For example, a fit and flare skirt or dress. A skirt or loose fitting pants with a high-waist such as palazzo pants. Stay away from head to toe flowing outfits if you are plus-sized. Your best bet is going to be something flowing that has a high enough waist that the hem line starts right below your breasts. Using the correct sizing is imperative when choosing this option, you want the outfit to flow away from your body to conceal vs pressing against it and revealing.
