From Jennifer Lopez, I would definitely take her clean, glowy, bronze skin. To accomplish this, I would start with a really sheer foundation for a fresh, clean look applied with MAC's 190 Foundation Brush. Then I would use a gel stick blush instead of a cream or powder blush. I'm really excited to buy Stila's Color Push Ups at Sephora, they look so fresh and give a naturally flushed glow. I would then go over the gel blush with a light dusting of powder bronzer... While I haven't bought it -YET- I hear that NARS' bronzer in Laguna is fab! Be sure to also brush the bronzer over areas where the sun naturally hits your face - ie. nose, chin, temples, etc.
I also like the way she does her eyes, as she uses mostly neutrals to tie in nicely with her fresh, natural skin. I would do a pearly/shimmery base colour like MAC's Nylon or Shroom eyeshadow all over. Deckchair pigment would look nice too. I would also dot some highlight colour on the inner corners of the eyes as well. Then I would take a shimmery medium brown colour like MAC's Sable, Antiqued or Mulch in the crease and outer third. I would also use some of this colour to softly line the lower lashline. For eyeliner, I would go with a dark brown colour, like MAC's Dipdown Fluidline to line the top and bottom lashes. A nude eye pencil to line the lower rims of the eye is an optional step, but helps to really open up the eye. Black mascara and you're done!
And of course, it's all about the LIPS for Angelina Jolie! Because her lips are already perfect (damn her!), she usually doesn't do too much to them and keeps everything really sheer. I would take a neutral lipliner like MAC's Spice or Subculture to line the lips, slightly outside the natural lipline for the illusion of volume -
it is, after all, Angelina Jolie...
Be careful not to go too far outside your natural lipline or it'll look really fake. Then fill in with a peachy or pinkish lipstick like MAC's Viva Glam V, which is a Lustre so it would nice and sheer. If you still want fuller looking lips, take some lipstick a few shades lighter and apply to the centre of the lips only. Finish with a light application of sheer gloss.
Damn, now I want to try this look tonight!
