I am loving the Epi Noe but I am not sure whether I should go for the petite or the large size. I love the petite because it's so cute but I carry a ton of stuff with me every day, so that makes me lean towards the large size, but would it be TOO big on me? I'm only 5'4, medium build. If anyone owns both sizes of the Noe I would be forever grateful for pics!!! TIA!
