I'm 5'1 (on good days) :shame:and I have both the Ramona and Riki and I prefer the Ramona. I the Ramona's roominess and take it with me more often thean my Rki.
Ramona is definitely too big. I am 5'8" and wear heels and it's too big, imo. I saw a girl about 5'6" or so and she had Ramona and it looked way big and didn't hang right. I vote for Riki, it's not as roomy so doesn't hang weird
Well, I'm 5'3" and I have a Ramona and love it. I tend to carry a lot for work, so I use it as a work/travel bag. I don't typically carry it during the weekends.
