I've only tried Leighton Denny polishes once before (see it here) and I really wasn't sure about it. However I think it was purely that the colour wasn't for me.
This one is called Get Your Cote and is from the new SS13 Riviera range, available in stores from 1st March. This is the brightest colour in the range which is probably why I went for it, as I just can't seem to get on board with pastels.
Totally in love with it, it's the brightest pure blue you can imagine, and is certainly cheering up my holiday blues!
