I am about 5'4" and size 2/4, medium frame. I keep going back and forth between the regular Damier Speedy 25 and 30. I already have a Mono 25, which I sometimes feel like is a bit small (in size, not capacity--I don't carry all that much around), but the 30 seems too big on me. I'm afraid that I'm going to regret getting the 25 because it may look too "young" or cutesy when I'm older (I'm 26 yrs old). Just get the 30 and hope that I get used to the size? I would really appreciate your advice. Thank you!!
