So I'm thinking of buying the Trevi PM. I have the Monogram Speedy 25 and the Neverfull MM along with a Vernis Reade PM. My friends are telling me that I have enough Monogram, but I was never really a Damier fan until I saw the Trevi. Trevi PM owners, what do you think - do you wear it more as a shoulder bag or a hand held -Pro's and con's? I need your advice. Thanking you in advance.
