Thanks everyone for the help with the Brooke....
Beerjeery, that make up bag is in fact genuine. I'm not so good at new Mulberry's regarding fakes but anything pre a couple of years ago/vintage I'm pretty good. I've sold a few of that range and have a similar bag myself....the colour is a nice shade of purple with bright pink stitching, the leather is harness leather, smooth, sturdy and thick....and the lining and inside tag is correct.......I bought my bag direct from Mulberry in 2001, so this bag is around the same age.
In the listing they say brand new.....which can be confusing, it would be in brand new Condition, but is in fact around six years old.
