I actually never knew anyone in high school who was made fun of for what he or she wore.
Same here. And it did happen occaisonally in middle school, but the exact opposite of what these people are claiming, the kids picked on were the ones wearing expensive clothes. One of my friends got suspended for a week for beating up a prep, it wasn't for that reason of course, but rather that the kid was a complete dickhead who had it coming, but I heard plenty of kids congratulate him later for giving a black eye to an "Abercrombie wearer". My friend also belonged to one of the most affluent families at my school, and they could've easily afforded expensive clothes if he wanted to.
