I've never rated any of it. Had some foundation which always made me feel greasy. Find the eyeshadows had much less staying power than MAC (though everyday I have MUA. At that price, I'll reapply!). I have a lipstick I like, but it's not any better than a No. 7 one i have.
I'm a huge fan of Bobbi Brown, I've tried lots of different brands from cheap to stupidly expensive, but always end up using Bobbi Brown. However I only use Bobbi Brown for my face base, I prefer Nars and Urban Decay when it comes to to the eyes and use Clinique for lips.
Hmm I had a makeover at the BB counter in House of Fraser back in 1995 when I started my first job in the West End. It gave me lots of ideas, and I go back every now and then to get more. For example how to apply eyeliner and do my brows, but have to say that the reason I have BB in my make up bag is more to do with sentimentality. The brushes are great, the eyeliner one I bought in 1995 is still going strong. Benefit or Mac are probably better. when I've used up my BB I'm going to MAC!
