I've never been a big makeup wearer but I'm trying to embrace it a bit more. I'm nearing 40, mousy (highlighted), quite sallow skinned, grey eyes. I fancy a red lipstick...ive got a new shirt that I love with pops of very cherry red in it and I'd quite like to wear a lipstick to go with it, but I'm not sure I've got the nerve. My teeth are ok. I just don't know what shade so help me be brave and feel fun and frivolous.
