The excersizes you're doing for your butt also work out your quads, hamstrings & hip flexors, so you'll be working on toning up your legs too. So, it's actually a good thing that it's mostly fat, since you can slim them down (and help your butt look bigger). You can also add running (great for the butt & will help lose fat on your thighs). And quick short distance sprints are great too. Those work your fast twitch muscle fibers and will really help boost your booty. (Think sprinters and gymnists in the Olympics. They all have great butts! Those are from working fast twitch fibers.)

Yeah, just any panties or bathing suit bottoms that cover your butt well, like full coverage or boy short. Even tight gym-type shorts would work. The less holes, the better. You can just hold them up where a light is behind them (and open the panties to where you're only seeing the butt part of the fabric, instead of both layers of front & back). Hold up several. The ones that are hardest to see the light through would be your best bet.
