- a good black eyeliner. i wouldn't necessarily recommend blacktrack, as not everyone likes gel/liquid liners, plus, it pretty much requires the additional purchase of a brush. i'd say get a black shade of whichever eyelining medium you like -- pencil, crayon, gel, liquid, etc. mac certainly has a lot of choices.
- a few staple shadow colors. a good brown/neutral, a shimmery highlight (think phloof, shroom, etc.), a gray isn't a bad idea for smoky looks (you don't necessarily need black, as you can use a smudged eyeliner pencil for black in a pinch), and maybe a few colors that complement your eyes, or colors you weara lot of. for example, i think a medium smoky blue is nice, a medium shimmery purple, and a mid-tone green. orange, yellow, and red tend to be a bit harder to work with. bronze and golds can look nice, too.
-a good mascara (preferably not mac), or false lashes.
- foundation, concealer, powder. whatever you feel comfortable with. it depends on the coverage. an MA could probably help you out once you figure out what you will want on a daily basis, and what you will want for more special occasions. tinted moisturizer can be a nice way to go if you want light coverage, studio fix fluid and studio fix powder are good for more heavy duty times.
- a bronzer or blush. powder or cream, again, play around with textures, see what you like. i recommend a good bronzer with a tiny bit of shimmery, only slightly darker than your skintone.
- lips. stick, gloss, lacquer. there are so many choices. start with a good, neutral lip liner, which you can fill your lips in with, and slap a clear gloss over. a good neutral, a good pink, and a good tan is a place to start. see if you can find someone on specktra or LJ selling a lip pallette or one of the holiday lip sets. they let you test numerous colors for a fraction of the price.
also consider a good primer. for foundation, prep and prime face is good, and for eyes, urban decay primer potion is the BEST. your eye makeup won't move, and you may even have trouble getting it off at night. to enhance color, shadesticks are the way to go. also, brows can make or break a face. keep your browns nicely shaped, and even get one of the many brow products mac makes.
pigment samples are the way to go, as are holiday sets, if you can find them for close to retail. get small quantities of numerous products until you figureout what you like, and what works best for you.
