I bought these nail lacquers when I was in LA, along with a metallic one in Lilac Panache, which the sales assistant actually picked out for me, I'll do a review of that one when I've tested it out.
Although I have seen a lot of reviews of American Apparel's nail lacquers on various blogs, I still didn't get my hopes up with them being from a clothes store and not an actual make-up brand. The AA website boasts 'one coat, opaque colour', the L'Esprit didn't fail to deliver that. The Supernova I was slightly disappointed with, it took a lot to get a decent layer of glitter on each nail as all I was getting was the clear liquid.
For me, £9 for a bottle of nail varnish is a bit pricey, although they do seem worth it. I paid about £10 for three bottles, so if you're ever in the States, I'd stock up over there.
