30 Proportions look great. Especially when opened up I think it would be plenty for everyday.I just got my first Birkin 30 in Vert Fonce and can’t wait to see how this beautiful shade moves and changes along with the lighting on a day out! Pardon the very UNglamorous photo I took with it in my hotel bathroom as that’s the only place where there’s a full length mirror! 😆
Initially, I wanted a classic black in 35, but when I previously saw this color in Seoul on display (the SA do not even allow my request to remove it from display to see it up close), i was so intrigued by how the color changes as you view it from different angles with the light, AND! The boutique I went to only has a 30, which I can just buy on the spot (with spending thrown in as well, though, but still, it’s a birkin on the spot! So I just jumped on the opportunity).
However, I am unsure if the size 30 is a bit too small on my frame, but I have a feeling that the 35 would be a bit too big for every day use!!
Oh, and I also saw the Maxi Kelly in the boutique and tried it on. Was actually almost buying this before the SA said that there is a Birkin! It looks OK on my frame, but it is so heavy and a bit too big in real life in my opinion.
The K40 looks like luggage/travel bag to me due to the width.
B35 could also work but they are pretty heavy and do you really need all that space?
Great colour! Wear in good health.
