Given the size of my nail polish collection, I'm surprised I haven't explored Butter London too much. I bought a couple of their Lips & Tips kits from TK Maxx sometime last year and while the glosses were admittedly dreadful, the formula of the polishes were outstanding.
I was recently sent the shade Giddy Kipper from their Fall 2013 collection, which consists of six polishes. This is the only colour from the collection that I find rings true to the Autumn months; the others being in-your-face brights, with neon pinks, oranges, yellows and greens.
Giddy Kipper is a beautifully pigmented indigo laced with shimmer. It looks beautiful in the bottle, and actually translates well onto the nails, unlike a few other shimmery polishes I've tried in the past. It takes two coats for opaqueness, and lasts a good 5-7 days with a top coat.
Although Butter London polishes come in at a pricey £12, their quality justifies it. I'll definitely be picking up more in future!
