I've used every mascara out there, or at least close to it... from Chanel, Lancome, Dior, Mac, Nars, Estee Lauder, Benefit, Cargo, and more! But my favorite so far and I'm on my 5th or more tube (which I've never been a repeat purchaser more than twice) is Loreal Voluminous False Fibre (non-waterproof). It add's a bit of length and thickness and I have very thin and short lashes. I've never gotten so many comments about how long my lashes are until I started using this product. 10$ at a drugstore too!
