I'm really lazy with this, I tend to use Clinique foundation, the light sheer one, same company as Estee Lauder, by the way.
I like a good pencil eyeliner but I buy whichever is cheapest, as long as it's retractible and doesn't need a sharpener, Maybelline is good, it stays put.
For lips, I used to spend a fortune (I'm an ex beauty consultant) however, these days, I think that with a lot of items you can get away without spending much and the best one for me is actually Rimmel!... Never thought I would say that but their long lasting stuff with the colour at one end and the moisturising balm at the other is probably the best I have ever found. I would rather a Rimmel long lasting lip than any of the dear ones. It just stays put, which is what we want when working.
