I looked at those links, and I guess they are pretty good, but to detailed fo me. I do my makeup everyday, and unless I am goig out I use the same colors. I put a powder base on my whole eyelid, on that matches my skintone. I can use my foundation b/c I only use powder founations. Then I put a shimmery gold on top of my eyelid, and I stop at the crease. Above the crease I put a dark silent kind of brown, and when I put it on, I make the applicator go out and up, if you can understand that. That is where the cat comes in. And then I take the same shimmery gold and put it lightly on my brow bone. Then I take an eyeliner that is the same color as the shimmery gold, and line the inner corner of my bottom eyelid. Then I take a black eyeliner and line the outer corner of my top lid, and go out and up like before. Then I take a clean finger and smudge both eyeliners, and the dark brown. Okay this sound difficult but it is really not, if I can find a pic i'll show.
And as for your hair, well my hair in naturally curly so most of the time, like in all of the pics that I post , I straighten it with a flat iron. And my hair also has natural layers. If you want it like jennifer's you basically want it to be bone straight right? Well to do that get a ceramic flat iron, and some flat iron spray like charles worthigton's. Part your hair (it has to be parted so that it is only one layer), spray on the cw then take the flat iron and put it on the root of your hair, and kind of bring it out like you are curling it and then go straight down. You may need to go over the ends again to get it really straight. And when you are done take a wide toothed comb and comb it all down. If you can understand my directions it should come out right.
