The dresses at the 2013 Oscars can be divided into three categories: tight and beaded, voluminous and interesting, and prom. The Atlantic Wire offers you the best and — let's be charitable — most unusual gowns from the red carpet, with closeups of beads, velvet, and tulle, plus the occasional haircut and refreshed face. The rest was all Chenoweth.

Tight and beaded

Jessica Chastain in Armani. She said she wanted to look "old Hollywood."

Closeup of the beading:

Amanda Seyfried said on the red carpet that she felt like her organs were being squished out of her body by her Alexander McQueen dress. Just like that squished cartoon lady behind her.

As more and more nontraditional roles open up for women in Hollywood, more and more actresses dress like it's the 1950s. Here's Jennifer Lawrence in Dior:

Prom dresses

In recent years, the fear of worst-dressed lists and mean Joan Rivers jokes has driven some actresses to wear the kind of boring dresses you see at prom. But this year Helen Hunt actually wore a prom dress — this navy gown is from H&M:

One reason clothes from H&M are so cheap is the fabric:

Anne Hathaway's pale pink Prada dress was a little revealing, or at least looked like it was revealing something:

Jennifer Garner in Gucci:

Queen Latifah:

Adele in Jenny Packham:

Her hair is very short, but it's not quite one of those high-and-swooshy styles worn by the likes of Miley Cyrus and approximately 20 percent of the humans in certain New York neighborhoods.

Reese Witherspoon in Louis Vuitton:

Fan Bingbing in Marchesa:

Jennifer Aniston in Valentino:

She is looking "refreshed":
