The Grammy Awards red carpet was a little more conservative this year, thanks to the dress code placed by CBS; unfortunately, the restrictions seem to have negatively affected celebrity attendees' styles.

While there were many fashion mistakes at the music ceremony, Rihanna stood out among the rest in her gorgeous red Alaia number, straying from her usual provocative style to adhere to the TV network's fashion guidelines (though she raised eyebrows when she confirmed her reconciliation with Chris Brown).

Two Broke Girls star Kat Dennings opted for Vivienne Westwood (seen after the jump). Though the blue minidress accentuates the 26 year-old's curves, it resembles too much of printed bubblewrap.

Though "Skyfall" singer Adele made quite a jump from her typical black frocks to a printed red Valentino piece, she kind of looks like a lifesize Matryoshka doll.

Beyonce, too, went with a look that is unlike her usual red carpet picks, truly taking a cue from the CBS dress code in a masculine, minimalist Osman suit.

One of the least flattering looks of the red carpet was a Tony Ward couture gown worn by Ashanti. Pushing the newly-imposed dress code limits - which prohibited certain curvatures from being exposed - the singer wasn't dressed her best in the black number, which featured a sheer bottom with floral prints.
