Barry M 66 Matt White.
I love Barry M nail paints, i've always been a fan of them. This Matt White colour is perfect all year round, and i think just always look so classy on nails as it looks a tad like a french manicure, (well, not really, but you get my jist) Luckily white, just like black, goes with pretty much everything, so you won't be clashing all over the place, and you'll have a nice clean look.
When applying this nail paint, i would advise 2 coats, waiting 10 minutes between each coat, and you get a really nice finished look. It's a bit gloopy, and 100% needs 2 coats as it's really doesn't look that good with just one coat, and looks kind of tacky. But with 2 coats, you'll have a lovely look on your nails.
