How to dres for my body shape?

Stop calling yourself wide and a blob. You are not. You have an athletic build. To dress an athletic body, I would wear shirts that accentuate your smallest part, below your bust. Also, wide straps will make your shoulders look smaller. An A-line skirt will be right for your bottom half, or any sort of tailored pants that are not cut skinny. In terms of dresses, I would try wrap dresses or faux wrap dresses, as they also define a waist. You're beautiful, don't sell yourself short.
