My SA is having a hard time finding a MM Picotin in my requested colors, but my store does have a PM. I saw it yesterday and of course it's simply darling. But I'm wondering it might be too small and look like I'm carrying my toddler daughter's purse. (I'm 5'4" -- SA didn't think it looked too small on me.) My SA says the difference between the PM and the MM is not very much. So, the question is, do I go with the PM just to get one now or wait?
