None, or at least very few of u, have perfect figures at any age, so adapting what we wear to our shape is always part of our clothing parameters.
My hips are very close to my ribcage, which means I have never had a proper waist and any clothing that cinches in at the waist makes my bottom look enormous in this, I do not need to ask. As a result, most dresses do not fit me so I have always tended to wear trousers or skirts with tops that skim over the problem area. Spine shrinkage has made the problem worse, butthe solution remains the same.
My sister rarely wore trousers because her legs were quite short, but she had a tiny waist, so she frequently wore the kind of dresses I avoided.
Looking smart is a state of mind, Wear clothes you enjoy and feel comfortable in and then step out with confidence, assumed if not actual.
