I've watched several Youtube videos and they recommend the 25. I'm a big girl - 5'8" and a size 12. I don't carry a lot of stuff. Actually, if I'm going to the mall or grocery, I can put everything I need in the pockets of my hoodie. Will the 25 be better for me, or will it look small? Someone on Youtube who seems to be the same size as me or a bit smaller said in Speedy she prefers the 30 but in the Speedy B, because it's crossbody the 30 seems to stick out. Which print do you prefer for this style?
