Should I get the Betsey Johnson "Good Girl" in the medium size or the large? I just can't decide. I'm a rather petite 5'4"- so I often look silly with big bags, BUT- I'm afraid the medium size might look too small? The medium is 12.5" long by 11" tall. The large is 16" long by 14" tall. I just can't decide. Please help (And no, I don't think I should get both- though that would certainly make things easier!) This is a picture of the large size. I don't have one of the medium on a model, so not sure how it looks by comparison. Thanks for your help!!!
