I've been really loving Essie nail polishes recently. They aren't available in Ireland (that I know of) so I buy mine online, the two below being my most recent purchases. Cocktail Bling is a pale grey/blue colour and Shine of the Times (another polish from the Lux Effects collection) is an opalescent top coat that can be layered over any colour you wish. I personally prefer to pair it with paler, pastel shades. I love Cocktail Bling worn alone, but I decided to try Shine of the Times over it and I thought it looked gorgeous!
