My Estee Lauder Double Wear foundation is the one cosmetic item that I will always have extras on hand. If they discontinue that item, I will cry! I've tried soooooo many different foundations and this one is the one that worked best for me.

I also LOVED the Shiseido Lasting Lift mascara and I found out that they discontinued it late last year! So now i'm on the search for my next "must have" mascara.

What are your ultimate "must have" makeup/cosmetic items?
