the XL muse and the XL nightengale are not that different in size. You have to remember that when carried the givenchy slouches A LOT A LOT A LOT, so the technical dimmensions are completely moot. Also, someone mentioned that the Traina sisters look good with the maxi but Ashley didn't. Well, Victoria Traina is NO taller than 5'2 (this is something I know, having stood next to her), probably more like 5'1, and the bag looks perfectly proportionate on her. So I think it all has to do with how its carried. Plus, I think most of the time the bag looks fine on Ashley, surely less dramatically oversized than a Balenciaga office or weekender.
