I actually think the 'Caramel' polish from the Nails Inc Diet Coke promotion is quite ugly - but I love it all the same! It might be my skin tone, but on it's own, the polish really is not for me.
For this mani, I've paired it with a dupe for OPI's 'Rainbow Connection' (Muppets collection) a mixed, fine & chunky, colourful glitter. I think this prettified the caramel colour a lot. This isn't a very hungry glitter polish, just one layer of top coat and my nails were smooth.
