I only wear concealor and translucent pressed powder. Everytime I attempt foundation, it looks really bad on me. I'm probably not foundation savvy anyways.
If I'm not going to work I don't wear foundation at all.
I actually rarely wear makeup (other than mascara, liner & brows) at all when I'm not going to work...and if I do, it's Smashbox Photofinish, concealer to hide my circles & loose powder.
