A combination of cycling and water polo has made it so no pair of pants fits me very well, though I haven't had a visit from the ass fairy (I have a tiny ass, but you can bounce a quarter off it and get two dimes and a nickle). I wear a 27/28 waist, but the thigh portion on those pants are so small, it makes me look like an alien.

But seriously, if you want to see bigger quads, try squatting five sets of 15 three days a week with a minute rest between sets. People will think you're on the juice.
