Don't worry, its not a 'thing' - you don't have to post photos on Facebook or get sponsorship for charity. Just something I'm planning to brighten up a dull January 
The idea is that you wear a different lipstick / lipgloss every day through January. I'm planning to stick all of mine in a big box and do a 'lucky dip' every morning. It will be a bit of fun (in a slightly pathetic way) and will be interesting to see which lipsticks I get excited about pulling out and which I'm maybe not that fond of anymore
Anyone else fancy it?
