Unhappy but also happy?

So I’ve been struggling recently with my weight. I’m not sure why but my whole body is proportioned weird. Basically, I can wear S,M and L as shirts and jacket. But when it comes down to my hips/butt I’m a L or XL and it’s so hard finding good dresses/pants/skirts. I’m happyish with my weight and body. I just wish I could fit into things better.

Any suggestions to help me out?

(BTW this dress is a L and ALMOST fit me perfectly but it was way too tight on my hips)
