You're buying from the higher end than most guys I know! Majority of the guys I know only have to drop big bucks on the dress clothes like nice suits and stuff (so i guess it kinda makes sense for ties to be expensive). Actually, I guess their slacks and button-up shirts aren't cheap either so just the t-shirts and jeans. Which is mostly what the guys i know wear. But no $100 jeans round here!
So I guess you're right. Just most of us girls do have to have more quantity. (for other girls; most guys don't ever remember what we wore)
