I'm not such a gloss wearer during the colder months because usually when I head outside and it's windy my hair ends up sticking to my lips and I hate it!
...but my lovely sister in law gave me this lip gloss for Christmas and I love it. I have been converted to a dark colour gloss lover :p
The gloss (or glass) I'm talking about is the MAC Pro Longwear Lipglass in 'Lasting Achievement'..
It's a plummy/burgundy colour (it kind of has the colour of red wine to me - it's hard to describe its exact colour). In the tube the colour has tiny gold shimmers in it but it doesn't show on the lips.
It lasts a good 2-4 hours depending on if you're eating/drinking etc which is quite good considering it's a gloss. I used this for going to the cinema and after eating huge amounts of popcorn and drinking cola my lips were still stained by the colour.
