Keira looks so gorgeous here. Her hair, makeup, and outfit go together seamlessly. The hair is quite complicated to do yourself, so if you would like it to look perfect, you should ask a hairdresser. The makeup is complicated as well, but you should be able to manage it.

Hair
I had my hairdresser do this style for a school dance. It was a really cute style and looked very good.
[01] Curl your hair.
[02] Start pinning pieces to the back of your head with bobby pins.
[03] Make sure your hair stays tousled on top by occasionally teasing your hair or running your fingers through it.
[04] Once your hair is all pinned back, you can loosen pieces and perfect your look.

Makeup
You will need lighter eyeshadows for this, like white, light pink and creme colors.
[01] Apply the lightest eyeshadow you have to your entire upper lid and extending to your eyebrows.
[02] Smudge a light pink into the crease of your eye.
[03] Use a darker color and apply a bit to your inner eye.
[04] Using a brown eyeshadow, apply a little on your eyeline to replace eyeliner. (Eyeshadow gives a smokier look than eyeliner for under eyes).
[05] Apply two coats of mascara to your top and bottom lashes.
[06] Use your foundation of choice to make your skin even
[07] Apply a very light blush to your cheek bones.
[08] Use a lipstick shade similar to keiras.
