Do You Prefer Size 30 or 35 Birkin?

I love the Kelly 32 for everyday, too! However, since I am short I prefer to have 32's in darker or more neutral colors. With brighter colors, I'd go with a 28.

Anyone have a Birkin 40cm? It's huge but if you're about 5'3" and above it would make the most stylish carry-on!
The 40 is very big! It is good for over night.I have put 2 pairs of shoes 2 pants and 4 tops plus make-up bag .I am 5'10" with out shoes.
 
Tks ASA for your suggestion...the problem is I can only get my hands on a 30 and 35 and not a 40...so I am not sure if the 40 is going to be huge on me.. I think to be safe, i will stick with a 35 as I worry the bigger the bag, the more I put and my shoulder can't handle...I am alreay getting back pain!!
 
I know I am going to sound nutty, I prefer the 30 and the 32. But lately, I have been thinking about the 35, just becos it's good to have a different size, kind of to have an all around collection :sweatdrop: (I am blaming on that fuschia ostrich 35 :heart:)
