Surplice or faux wrap style tops and wrap dresses are great Don't be afraid of tops that have a gently elasticized waist or a self-belt at the waist. Instead of adding bulk, it will help create the effect of an hourglass shape.
The most important accessory to wear is confidence. When you feel good, you look good. You stand taller, you have better posture, you rock your outfit, and people notice the whole package, the amazing woman, not one specific body part.
