I often walk past the American Apparel shop in Covent Garden, but I've resisted going in because everyone in there looks like they've just stepped out of the 'Being a Dickhead's Cool' video - if you don't know what I'm talking about it's here: http://www.youtube.com/watch?v=lVmmYMwFj1I (warning, they say 'dickhead' quite a lot).
I finally went in last week and bought this nail polish. Mouse is a straight taupe cream, perfectly balanced between brown and grey. It's more flattering on my pale olive hands than Rescue Beauty Lounge Grunge was; Grunge has a bit too much pink/mauve in it for me - you can see Grunge on Helen of Just-Nice-Things.co.uk here.
I got on well with the formula; two coats gave me good coverage and I found the brush quite easy to control. I think the price is good too at £7 each, or you can choose three colours for £17, particularly considering it's a 3-Free formulation.
