Good DIYs using old clothes?

My family is really on a low budget, but I've been really in clothing DIYs lately. Also, I've looked up stuff online before, but most of the DIYs are meant for really skinny girls, and I've got kinda big thighs and hips (i'm not fat or anything, just kinda bigger in those areas). Are there any simple DIYs I can do that will disguise my hips and thighs?
