They both look like 35 to me.... But for sure, Christine's is a sellier and Grace Kelly's, a retourne.
I agree. The proportions looks like 35s to me on both of them.
Stiller: sellier
Kelly: retourne
Personally, I prefer sellier on smaller sized kellys: 32 and below. Retourne for 35 and above (it makes the bigger sized bags look softer).
