"An Unforgettable Evening Benefiting EIF's Women's Cancer Research Fund" at the Beverly Wilshire Four Seasons was surely a great cause. But Reese Witherspoon, Taylor Swift, Molly Sims, Christina Applegate and Faith Hill made it unforgettable for quite another reason...

First, the "goods!" Reese's kicky frock walks the lingerie line, but is undeniably cute.

Taylor Swift is getting into greeting cards, but I actually wish she'd get into teen fashion and share her savvy with the youth who so badly need it! Well, she or her stylist.

Molly Sims' mulberry-hued Grecian is easy, breezy...well, you get the idea.

And now it gets dicey. The stunning Olivia Wilde's silhouette is stunningly unflattering.

Meanwhile, Faith Hill manages the elusive combo of trashy and dowdy found in certain La Perla lingerie.

Christina Applegate has the right idea about one thing: if you can't get the seatbelt off, just pretend it's part of the getup.

This Swan Lake thing, as modeled by Julianne Hough, needs to end. Right. Now.

I guess Angie Harmon just didn't think this was quite Conan the Barbarian enough on its own...
