I have both the 30 and 35 as well as a kelly in 32. I have to say, the kelly and birkin 30 are very similar in look, but the birkin holds much more. The 35 is so MUCH larger. You really don't realize it unless you see them next to each other. I use the 30 as a purse...can't really throw in a magazine or even a water bottle without it really stretching out the bag (esp with the basic cell/wallet/cosmetic bag/hairbrush/keys already in there!). The 35 easily transport all that stuff, but at a price in weight. Yes, it's heavy...but it is absolutely gorgeous. Both my blue jean 30 in clemence and 35 gold togo are brand new. I can't wait for the gold togo to look old. The blue jean, I will treat much more nicely. I will post pictures to try to give you a better perspective.
