CBS wanted no wardrobe malfunctions at this year's Grammy Awards, issuing a detailed memo ahead of time urging everyone to dress properly.

"Thong-type costumes are problematic," the memo read in part. "Please avoid sheer see-through clothing..."

See the full list of guidelines here.

We'd say Janelle Monae adhered most closely to the wardrobe memo, showing up in a posh tux-and-tails ensemble, complete with vest and hat. She did flash a tantalizing sliver of toe. 

Rihanna wore a sweeping and glamorous red gown while Beyonce kept it trendy with chic color blocking.

See all the looks here.

Adele was all about the flower power while Jennifer Lopez appeared to be trying to out-leg Angelina Jolie. (Is there a Twitter account set up for J-Lo's gams yet?)

Karlie Kloss and Kelly Osbourne showed strategic bits of skin. Katy PerryandKelly Rowlandpushed the limits a bit more.

Gotye and Kimbra looked sort of like a high school costume artist and his project.

Miranda Lambert took a daring plunge in front while Faith Hill seemed to strike just the right balance of sizzle and style.
