preach sister!
 

Hunny I had this problem when I was a size 3/5! Big booty and thighs and the terrible gap in the back which then always required a belt and then over time your belt looked like crap because it was so worn out from trying to keep your butt in your pants!! lol its worse now but still! lololololol!

Thanks guys for all the clothing recommendations! I'll definitely look into them :D
