A glitter crackle top coat, by 17. I bought it on a whim when I clocked it in Boots and on first swatch wasn't overly impressed, skip to a full hand application and WOW.
This is over two coats of China Glaze's OMG, which I think compliments it perfectly. The glitter on the crackles is so much better in person, but hopefully you can see it a little in these very SLR pictures.
Currently loving this top coat and experimenting with shades it will go with (FYI O.P.I's Do You Lilac It? is perfect).
Spotted in Newcastle, Eldon Square Boots for £3.99
