Bagfetish, you really need to try them on, the PM and MM look similar but they are not and the proportions between the handle drop and bag size are different or at least they appear different. You really need to to try them both to see. I think the PM might be too like a doll bag on me which is why I went for the MM but I have seen the PM on taller people than me and it looks great, I've since reconsidered the PM size for me and think I could work it, may be in a bright colour. That's another thing, what colour where you considering, it makes a difference to how the size appears, bright colours make the bag appear larger, black and darker colours male it smaller, know what I mean.
