kelly 32 is very good size for outside, the classic one is not that easy to take things out though, but from 2004, they have a kind of new bag, called kelly lakis, has two zipper infront and one behind. Mrs lakis is a famous greek fashion designer. He made the change.
but kelly usually use hard and good textured lether, for night somehow.
birkin.....much easier for everyday use.that's all.
anyway, price increase every year, and if you want to sell it, even it's an old one, you can cash it right away.
