My favorite neutral eye look is MAC Ricepaper eye shadow on the eye lid, MAC Soba eye shadow in the crease of the eye, and MAC Nylon eye shadow on the brow bone (it can also be put around the tear duct area beside the nose, and on the cheek as a high light).
For a lighter eye shadow look, I wear MAC Orb eye shadow on the eye lid, MAC Bamboo eye shadow in the crease of the eye, and MAC Vanilla eye shadow on the brown bone (which can be used for the same high lights as Nylon eye shadow).
Both eye shadow combinations are favorites of mine, and I especially love them because they cause every eye color to pop (my eyes are green, my mom's are blue, and my best friend's are brown.. it makes each color stand out amazingly!). Additionally, I that colors can be mixed in to give the eye make up a different look easily.
MAC Your Ladyship pigment is an excellent high lighter because it isn't too sparkle-y or flash-y, and is great for any where (brow bone, tear duct, cheeks..). I also like that I can mix it with other products (I prefer products with many, many uses to I don't have any make up just sitting around being unused.. MAC is too expensive for that! I can mix it with other pigments to add shimmer and/or lighten them, with lip gloss for shimmer/to lighten, and over other products to tone down the color. Lovely Lily is an other pigment that I think is appropriate. It gives a sheer wash of a purple color with out being inappropriate.
I'm an NC20 (adjust the color of your product accordingly), and I use MAC Mineralized Skin Finish Natural as a bronzer/lightener. It's amazing!! Where MAC Strobe Cream of Revlon Skin Lights makes skin look beautiful, this does the same, but is more appropriate for the work place. It's also very helpful for contouring all areas of the face.
For a very natural blush I use Maybelline Dream Mousse Blush (I use Peach Satin). Because it's a mousse, it lasts a very long time, and if you prefer using a powder blush additionally, it'll act as an excellent base to help keep your powder blush on longer.
Revlon Lip Glide lip sticks are also ideal. I use the sheer lip sticks (labeled "Sheer"). I have a bronze one and a light raspberry pink one. Find a color that you love!
I'm sorry for the novel that is this post! I realize this isn't a list of what I do/wear to work, but it was the best way for me to share the products I recommend.
