I know this is a silly question, but I still need to ask. I have a cerises speedy and it is the perfect size for me. Every time I go to the LV boutique I always have a different bag with me, and never my cerises. Every time I go, I try on the damier speedy and I swear it's smaller!! I just want to make sure that I'm not crazy and that all 25s are the same size. They don't vary by model (mono, damier, cerises, etc) do they???
