Today I'm wearing Boots No. 7 Speed Dry in Poolside Blue. I love this blue because it's not too dark or too light and very much fits the nautical theme/trend.
Two coats were required for complete opacity though you could get away with one. I've noticed with the No. 7 polishes the lacquer thickens on the brush quite quickly so it can get a bit annoying having to recap and shake after 2 nails. This one is speed dry but it definitely happens on the stay perfect ones too. The tall bottle is a bit of a design faux pas as well.
(Update: Slight tip wear and chip after one day of not doing much :-( )
RRP £7 (£7.50 if you're in Central London, what?!?!?!) luckily had a £5 off No. 7 voucher!
