First things, first. I know that if you're not from the UK, you're probably wondering what in the world is a dodgy barnett? It's slang for "bad haircut" and it's the name of one of butter LONDON's fall/winter 2012's colours.
butter LONDON describes Dodgy Barnett as a highly holographic shade that blues the line between grey and silver.
This was my first time trying a holographic polish although I've seen (and been fascinated) by photos. I love wearing grey and silver on my nails so this was a no-brainer for me to choose. The holographic part of the polish is multi-coloured - but the stand-out colour is orange and yellow.
The photo below shows a three coat application. The glitter in it is very, very fine so it went on smoothly (chunkier glitter makes the brush drag on the nail). As each layer went on, the holographic effect increased. If you wanted to use this as a holographic top coat this would work over another colour very well.
I love this polish. I couldn't stop looking at my nails while wearing it, which actually was an impressively long time without any chipping (under a top coat). It went on smoothly, dried swiftly (as all of the butter LONDON polishes I've tried do) and it wore well. I also liked that this shade doesn't scream fall/winter - it works well as a transition shade and the holographic nature is intense in bright sunlight.
