It's all very hush hush, with both stars and designers working hard to keep their red carpet fashion choices a secret, but that hasn't stopped the speculation surrounding Oscar night fashion.

According to Bronwyn Cosgrave, author of "Made for Each Other," a book on Oscar fashion, actresses should shoot for "sexy and refined" when choosing their look -- finding the classic, vintage look that is also in keeping with the growing trend towards individuality.

Cate Blanchett, Nicole Kidman and Uma Thurman top the fashion-forward A-list for Marcy Medina, West Coast bureau chief for Women's Wear Daily. Because of the recent runway success of "bubble" skirts, she things these actresses might go all out with big gowns heavy on volume.

It's also rumored that Giorgio Armani might be dressing one of the most impressive stars, as he's holding a couture show in town the night before the awards. But players at Fantasy Fashion League (where you get points depending on the media exposure of your favorite designers and celebrities) also put Chanel and Dior in the running for top designer on the big night.

What do you think? Who will have the hottest looks on the red carpet this year?<
