A mega popstar like Christina Aguilera might be able to pull off blue, pink and white eyeshadow. But you shouldn't try. Pick a color that complements your eye color. Never match eye color. Stick with a monochromatic palette, and apply with a very light touch.

Jennifer Aniston made boho braiding work with an incredibly glamorous beaded gown. The trick is to keep the braiding simple and integrated into the rest of the hairstyle -- loose waves work best. Hide the end of the braid to avoid looking like a tween.

Kim Kardashian looks more like she's struggling with a bad hair day than a boho girl who just came from the beach. The braids are too tight compared to the rest of her hairstyle. And, let's face it, boho braids and batwing eyelashes just don't go together.

Angelina Jolie usually plays down her full lips, but she picked a winner with this shade. The color is rich, not bright, and it complements her skin tone. Keeping the rest of her makeup simple, allowing the lip shade to take center stage, rounds out this look perfectly.

Once again, Miss Xtina goes all out with a look, and it works for her. But hot pink lips, combined with strong eye makeup and fake eyelashes, won't work for you in all likelihood. Choose a pigment rich shade that leans a tad towards its closest neutral cousin. Select a color that complements your skin tone, and keep the rest of your makeup neutral and simple.
