MAC obviously. =)
Shoes - more specifically, ballet flats. I'm afraid they will be out of style soon and I won't be able to find them anymore. =P I have pointy-toed houndstooth, grey wool, black satin with a gold buckle, zebra print, camo, 2 pairs of plain black with a bow... and plans to buy purple satin ones.
Earrings! I don't wear necklaces often, or bracelets (they get in the way of typing at work) but big chandelier earrings are a definite must-have for me.
And purses! I get bored and switch them up quite often (large bags for work especially.) My current favourite (and latest purchase) is a large, rectangular, dark teal snake skin with large gunmetal O-rings. *heavenly sigh*
At least with funky shoes, earrings and bags, I can wear all black, or jeans, and it always looks different.
