I'm 5'7 and about 135 lbs. I'm definitely not in the petite category. Would the 30 be the best size for me? I feel like the 26 would be too small on my frame.
The drop on the strap of the 26cm may be short for you. I think the 30cm would be perfect. I am quite a bit shorter than you at 5'2 and like both the 26 and the 30. The 30cm definitely sits lower on my body and would probably be more comfortable on your frame. Are you able to try both sizes at the boutique?
