Hi and Congratulations on your upcoming purchase.
The TREVI is certainly a beautiful bag, I have it in the PM size and absolutely love it. I read all of your requirements and have a good sense of what you would want and in my opinion, I think the size that you would be most comfortable with is the PM.It is still big enough to make a statement but not so huge when carried on the shoulder that the base part is big and bulky. Sorry no pictures of me wearing mine, but I have been told that I have a way of finding the perfect size, colors and styles for people, both friends and strangers have complimented me on this throughout my life. I think you will be very happy with the TREVI PM and when you get him, come on over to the TREVI CLUB and introduce yourselves to us.
with your height thats a tough one.. I have the pm, I like the shape of the PM better:
I'm 5'2, in this shot i have 4 inches heels, so 5'6, teehee. about 115
I use the long handles to carry on my shoulder.
I dont have either but tried them both on at the boutique. I am 5'10" tall and even I think the GM looks more like luggage than a bag. Its HUGE! I would definitely go for the PM. If I ever got one, it would be the PM.
