I have that exact bag, the exact same color. It's one of my favorites! It's a good size without being too big, easy to get in and out of and it even sits on my droopy shoulders without slipping off at all. One of many reasons I LOVE Prada is they seem to be the only bag designer that knows how to design a shoulder strap that stays PUT!
I've said more than once that if I was told I could only keep one of my bags, that this would be the one.
