If I were styling that for a photoshoot, I would do a deep brown on the eyelid in a circular shape. You can take a deep brown liner on the top (lightly) and bottom and feather them out. Take a white or lighter brown line on the inner rim to open and brighten your eye. It's clean and classy.
Hmm as per the other thread, if you're pairing the dress withblack trousers and going for a evening look, I'd make the brown shadow a dark brown and make a black thicker liner on the eye. Good luck :)
Hmm...interesting Matinee - sounds v nice...got any examples of your creating thinking?
