NOTD: Pastel Purple

This pastel purple I'm wearing on my nails today gets me soooo many compliments and people never believe me when I say it's from George at Asda and only cost me £1.52 a bottle! The colour goes on really well but the bottle and brush are small so it can be a little fiddly. You could get away with 1 coat but I went for 2. The only real gripe I have with it is the weird little blue ring forming around the top which is visible in the first photo- can anyone explain this?
