Port-a-Loo-Blue, Roll-In-The-Grass and Bestival Blue have been on a permanent rotation on my nails for the past month or so, and I haven't gotten sick of any of them.

Port-A-Loo-Blue kicked off my new obsession - it's a bright colour pop of teal that looks great with a summer glow. I was soon back to Boots for more and bought Bestival Blue - an eye-catching pop of cornflower blue with a hint of lilac. Just divine. Roll-In-The-Grass proved another hit - a minty pastel green with enough punch to hold its own against the brighter shades.

These polishes have it all - they're easy to apply with Rimmel's wide but precise brush, they dry in a jiffy, and leave a super-shiny, long-lasting finish. I get at least a week of wear out of each application when applying two coats with a top coat to seal.

As an added bonus - the polishes are only €4.99 each, and Boots currently have a buy one get one half price offer on selected Rimmel products. Absolute bargain.
