I understand what you're saying. You don't want what everybody else has. I bought my Hamilton's and bam. Hamilton's everywhere. I don't care what everybody else has. They have the same bag, more power to them. The outfit I wear with my purse is always more dressy, and I see people just being casual with it. (Jeans and sneakers) More power to them if they're happy.
You shouldn't let the local female population move you out of a brand because it's common. I liked MK a longggg time ago and never could afford it until this year. It's what I like and I'm not going to let my common "hot" brand leave my house because I see it everywhere. It's what I like, and it makes moi happy.
Maybe you need to buy another MK that's just right for you and not seen as much. I'm having fun with my MK's and I get compliments all the time. The only bag I see that everybody else has is the black Hamilton. I branched away from the typical colours seen and I get the oohs and ahhhs. Don't worry about what everybody else has. Be happy with your MK,
