I have for you today 'Maida Vale' by Nails Inc, which I just bought yesterday! Normally I say a firm "no" to £11 polishes but it was 3 for 2, I'd just gotten my student loan, the sales girl raved about my stamped nails... and they are pastel full-cover glitters! They looked amazing! Heehee. So I now own all 3 shades and do not regret it.
Maida Vale is silver with a lilac hint to it, which comes through depending on the light. It's a mix of micro glitter and larger hex pieces. Here are 3 coats with plenty of top coat:
OK, I really freaking love this polish. It genuinely looks like I have crystals encrusted on my nails. It just looks SO GOOD.
As with other "3D" glitters this needs plenty of top coat to tame the gritty finish (I used 2 coats of Boots Essentials top coat as it's quite thick, and finished with a coat of Sally Hansen's Super Shine), but that's to be expected.
Is it worth £11? I will never be 100% behind such expensive polishes, but this is the closest I've come! If you can afford it I say go for it.
