OK so you might think scented nail varnish is a bit childish - I can see that - but since I started using it last year it's become a key component in my commuter arsenal. Stuck next to the smelly guy on the bus but too British to hold your nose? Strike a pose - holding collar/necklace, touching glasses and leaning on my hand are my winning moves - and let the fruity aromas waft from your nails to your nose, blocking out odours from less fragrant travellers. The sparkling pink Grapefruit Fizz edition pictured above from the Revlon SS12 Scented Nail Enamel collection, is particularly delicious. This new range of glittery polishes also comes in Grape (purple), Pineapple (yellow), Watermelon (cerise) and Orange. £6.49 each from Boots and currently 3 for 2.
