For one of the sexiest beauty tricks there is, try a set of lash extensions. Avoid a full set if you're over 40; individual ones just look like your own, only more gorgeous. Try Tint & Lash at Blink, £72, which last two weeks or more. Want to try it yourself? Then pop a cluster of four or five Ardell Individual Lashes, £5, to the centre of the top lash to really open up the eye.
