I love MAC shadows, brushes, and lip products. I never thought they'd have the mascara from hell. I got fake lashes there for New Years though and those were awesome. If you buy them, they'll put them on for you. They looked really cool.
Daisy-- MAC makes a lot of awesome brushes. I saw that clinique just came out with their own line of nice ones too. I have a mix of Mary Kay brushes (which I love) and MAC.
I used to have an estee lauder brush that dropped tons of hair on my face. Nothing makes a woman feel sexier than black hair on her face.
