Off of the top of my head:
Tools- disposable mascara wands, lip gloss wands, spatulas, tissue, tweezers. a towel, brush cleaner, hand sanitizer, alcohol, pointed qtips, CDs (to use as palettes)...
Makeup- foundation palette, blush palette, eyeshadow palettes neutral, brown, highlight, and pinks, variety of nude lipsticks, liners and glosses (usually nudes and light pinks), eyeliners in brown black and white, false eyelashes (singles and strips), lash glue, different kinds of eyeshadow base, photofinish, moisturizer, invisible set powder
Misc. Breath mints! A towel, a bag to throw in dirty brushes (do you don't mix them up between people in the bridal party), an apron. and extra business cards
That's all I could think of off of the top of my head. Hope that helps some.
