I recently "re-bought" my MAM in black since I had lost it last summer (thanks United Airlines...). I got a good price at the online Black Friday sale on the RM website, but I must say I was pretty disappointed because the weather is so pebbly and the lining horrible ( I just don't like light coloured linings...)
My old MAM was smooth leather with dash lining (from the RM NYC collection on her website, bought in December 2012)...I miss it so much.
I had inquired by email before to learn whether you can know (at least) what lining you will get, but was told you can't....I think they should do something about that. Sometimes I almost prefer to buy on other websites just because of that (you can see the lining and leather you will get).
I take the opportunity to claim that I miss darker linings and smooth leather....and rose gold hardware
