Models Own - Champagne isn't a dark wintery colour but I think it is perfect for autumn. It adds a hint of glitter in it so it gets you excited for Christmas and winter. I think this nail polish is quite subtle as it looks natural.
Barry M - Red Glitter is the ultimate Christmas nail varnish, it is Santa Claus red and glittery. What more could you want in a winter nail varnish. You have to wear this on top of a red nail varnish unless you want to use five or six coats of it.
Avon - Matte Grey, I surprised my self with this polish because I thought I would really like it, but when I tried it on I didn't think it looked very nice. This was mainly because it looked streaky, so I add a clear coat on top and now I love it. I wanted to involve this because I think grey is the perfect A/W colour but this is the only grey I own.
Avon - Midnight Plum, I own a lot of purple nail varnish but none as dark as this, this is my favorite purple nail varnish because of how dark it it. I thin it is ideal for winter because it will go with a lot of outfits as it's not an obvious colour, it is very dark, almost black.
What colours do you love wearing in autumn and winter?
