The hosts of prestigious events are expected to be poised, funny, quick... and, it doesn't hurt if they look amazing. Anne Hathaway is gorgeous all the time, but she had a ton of help from names like Tiffany, Armani and Oscar at the 83rd Academy Awards on Sunday night. Even after we've taken a very critical look at each of her stunning gowns, we're finding it pretty hard to find flaws. The beautiful Valentino number she wore on the red carpet was just the beginning of an eye-popping night of fashion.

After strutting her stuff in bold red, Hathaway slipped into this draping white Givenchy Haute Couture by Riccardo Tisci number, a jewel-bedecked floor-length ball gown that really helped her sparkle on stage. The soft look was perfectly paired with a simple, side-parted hairdo that left one ear exposed to show off her matching diamond jewelry from Tiffany's.

The actress boldly donned a black Lanvin tuxedo, custom-made for her small frame, to perform her big musical number of the night. She's still wearing the Tiffany diamond earrings (price tag: $60,000), and chose fantastic Brian Atwood heels to set off her shining musical moment.

Anne Hathaway returned to glamor with this Vivienne Westwood frock. The black ball gown is embellished with an embroidered silver design that picks up the sparkle in the $10 million Tiffany necklace around Hathaway's throat. The lovely updo clearly displays the sweetheart neckline, elegantly completing Anne's lavish look.

The Oscar co-host had a lot of fun in this fringed silver frock designed by Oscar de la Renta. Her long locks are casually parted down the middle, with a loose wave to that mimicks the loose motion of the sparkling dress.

Floating chiffon gives this sparkling purple stunner from Vesace an elegant look. The gown has been beautifully paired with Anne's low, loosely gathered-bun of dark hair. Dangling Tiffany earrings complete the flowing, sparkling ensemble.

Hathaway showed her sleek, sexy sense of style with this Armani Prive sensation, a shining violet sheath with classic lines and an off-the-shoulder design. The color is perfect for Anne's tanzanite and diamond earrings, designed by TIffany, and her straight, shining hairdo.

Anne closed the show with a jaw-dropping, form-fitting A-line gown by Tom Ford, her hair once again pulled back to reveal sparkling Tiffany diamonds in her ears. The  deceptively see-through and crystal-strewn black gown is so sensational, it's no wonder she saved this fabulous frock for last.
