Ladies, I desperately need your help! I know that I want to get a Speedy, but cant decide between the 25 and the 30. Since I am 5-9 I think I should get the 30 (since most people suggest the bigger size for taller people). But I love the cuteness of the 25, but also, I like the idea that I could use the 30 for school as well (since its bigger), and I do have other smaller bags that are comparable to the 25. Also, everyone says get the Damier, especially because the handles on the Mono Canvas get very dirty, but I am very partial to the Mono Canvas HELP ME!
