Hi, It really depend what LV bags you already have. I personally like the bloomsbury more. I love the pleat in the middle. If you already have too many monogram canvas in your collection, then go for bloomsbury for a change.
I tried them both on today both GM. I am plus size. I love the Odeon and it is wider, but I am not a Vachetta fan. I tried on Bloomsbury and put my stuff in it and it fit. My mother even loved it and she gave me 100 on it, i had a 100 gift card and Saks charged the rest, so Bloomsbury GM is mine!!
