You probably know what I'm talking about...

It's a giant square. My body is exactly the same width from hipbones to thighs and I find it really annoying. However, I don't have a flat and square bottom - it's round and prominent.

I have no idea what to do. Is there any way to soften those vertical lines and not to add any volume to my hips? I look even more pear-shaped in voluminous skirts and dresses.
