I have nearly bought this colour from H&M so many times! It's so vivid it all ways catches my eye when I'm shopping.
I have to admit I'm a bit of a nail polish snob and prefer the well known brands, however I threw my snobbery out of the window and put in my basket!
I love it! It's such a bright blue, I have nothing like it!
It applied well, this was two coats and it only cost £2.99! I'll see how it wears then I may check out some of the other colours in the range.
