Brushes- I would go with a set from Sephora (best prices and quality)
Eye shadows- Mac!!!!!! Mac has great make-up..especially eye shadow
Foundation- If you go to the Mac store, you can try different types from sheer to full coverage. Otherwise, Bare Essentials is very good.
Mascara- I am using Lash Blast from Cover Girl and have had many compliments. My lashes are long but very thin.
I hope this helps!!
