Some looks you want to replicate this Spring/Summer for this body type are:
1. Trouser style jeans...they are AWESOME at hiding your bottom, esp. if you have "saddle bags".
2. Tops with lots of frill and details at the top. If you're small chested you can get away with SO many types of tops, such as higher neck lines.
For jackets DO NOT allow the bottom of your jacket to hit at you hips.
DO NOT DO THIS:
Rather, your jacket should hit above hip bones or closer to your waist, I know you want to just cover up that larger bottom area, but the above pictures just accentuate it.
