I've been nicknamed 'Tara Mascara' since I was like 16, if that tells you anything, haha.
I love mascara. The more the better, I say, as long as it isn't getting clumpy or TOO spiky. Super long, thick, and dark. I only use black. Sometimes I only wear mascara, and some of those times I only put on a light coat, just enough to darken my lashes and make them more visible. But generally I wear it pretty heavy handed. =P
I'm pretty picky about the texture of it though, I don't like if it stays too 'soft' because then if I wipe the corner of my eye or something, lashes move and then tend to stick together, which feels really irritating and I keep f.ucking with it. So I tend to buy like a million mascaras to try them out, and only end up liking maybe half of them. One of my favorites is Hard Candy 'Lash Call' mascara. Black.
I wear it everyday. But I don't cake it on... it is expensive but my favorite mascara is always Lancome Definicils. To me it is perfect. It is the 1 thing in my makeup that I splurge on. I just recently I took a break from it and picked up some cheaper stuff and it is working out okay. Maybelline? The popular pink tube except this 1 had a black lid. When this runs out, I'll probably try Lancome's newest mascara. Oh, and I always use black/super black.
