L'oreal Bare Naturale gentle mineral powder in Soft Ivory
This is by far the best powder I've ever used.It is really light.
Gives a great coverage assuming that it is a powder,not a foundation.
It comes with a brush,but I don't recommend using it because it is harsh and its shape is not the best for applying a powder.Better get a big round fluffy one.
My colour is Soft Ivory.
I got it from fragrancedirect.co.uk for about £4.
