I've always wanted the pm but the most popular seems to be the mm. After a 2 year LV ban and lots of thinking (plus help from TPF) I went with my heart. I don't carry a ton of stuff and I find the size can be dressy or casual. It's great for walking around downtown or out for dinner. I like that I can wear it on my shoulders comfortably. I've also heard that cracking may happen if cinched. You don't have to cinch the pm as it's small enough as is😊. It's a great bag and I'm thrilled with my decision. If you'd like pics with my stuff inside let me know....
