I'm going to assume you mean you're just wondering what you need for personal use? Not doing makeup on others? I don't know.
Some basics:
-Eyeshadow base, I use UDPP as well as a lot of the other girls here.
-Black eyeliner liquid and pencil. Wet n Wild's pencils are great and cheap.
-Foundation. I keep a mineral foundation from EDM for everyday and a MF pan stick for more heavy coverage, I got lucky that one of the panstick shades blends into my skin flawlessly.
-Concealer. I just use my mmu with a concealer brush, but if you don't use mineral makeup a good concealer is key. I do have a green one to mask any redness that might pop up.
- A really good lip balm. I keep 3 with me at all times. Burts Bees, Mark soothing balm, and aquafina lip oil. No lipgloss or lipstick looks good on dry flaky lips.
-Eyelash Curler
-A good mascara. I have bazillions, but some good cheap ones to start out with in my opinion are MF 2000 calorie, Lash Exact, and Maybelline Volume Express.
- At least a couple blushes. One for a natural look, and one thats a little flirtier. I like Nars Orgasm for natural and Mac Dollymix for a more bright pink.
-A perfect nude lipstick. A nude lip is great with a dramatic eye, and wearing nude lipstick under any gloss is pretty.
-An everyday e/s combo. Like a tan for the lid, chocolate for the crease, and a highlight.
-A smokey e/s combo. Weather it's gray, black, purple, whatever works best for you.
-Lipgloss- I like Mac lipglasses.
As far as brushes go for starters I'd get a good blush brush, eyeliner brush, e/s blending brush. Sonia Kushak at target makes good brushes, for a good price. And for your foundation it depends on what kind of foundation you use and how you like to apply it. You may need a foundation brush, a kabuki, a sponge, whatever.
