I consider myself fortunate to have a career that requires me to dress up. My style is generally laid-back, so sometimes I need a nudge to change out of my favorite jeans. This year, I attended my first Academy Awards ceremony, and the dress I wore to the Vanity Fair after-party -- a slinky red gown by Zuhair Murad -- was one of my all-time favorites. As soon as I put it on, it felt right -- it was love at first try.

Here are a few tips for the next time you have to pick out a dress for a special occasion:

1. Go shopping on a day you feel good. If you're bloated or coming down with the flu, you're not going to like anything, anyway. Only shop when your confidence is up.

2. Remember that the dress will look even better on the actual day. Your hair and makeup will be done, and you'll be wearing a great pair of heels. (I wanted to match my lipstick to this dress, and I love the classic result.)

3. Fit is everything. If it's pulling or falling strangely in the dressing room, walk away.
