Yay, Sinful Colors available at boots in the UK?! And in the 3 for 2 offer, don't mind if I do. I was actually away in Nottingham when I was lucky enough to spot these as they weren't being stocked in the Leeds city centre store. Here's the first one I tried, Glass Pink
This is 3 coats, it's really sheer so you'd need something underneath if you didn't want visible nail line. It's so pretty though, beautiful and shimmery.
I managed to snag Cinderella as well which is the one I'd really been lusting after, not been in the mood for blue nails though so haven't tried that one out yet,
