Oh, dear
@TraceySH, what you are doing!!!!
I was in the city yesterday and dropped in the Dior boutique. I agree with you, concerning the sizes. Medium is also the perfect size for me. That exotic bag in your picture captured my attention much, her colour. Unfortunately, the boutique offers either a white bag or a black one. They heard nothing about the other colours and my SA was upset that our country's boutique is beyond everything: limited sizes, limited colours, limited stock and very difficult to transfer stuff from outside the country.And we pay a premium.
I have to admit I get more information on the forum that in the boutique.
