Britney's got another fashion blunder under her belt.
The singer, 28, hit the Grammys on Sunday in a bizarre black, long-sleeve lace dress with black body suit by Dolce & Gabbana.
Even though the "Womanizer" singer lost out to Lady Gaga in the Best Dance Recording category, she appeared to be in good spirits. (E!'s Ryan Seacrest noted that she "ran by" him on the red carpet with "an entourage of 100.")

"On my way to the Grammys," Spears tweeted before the show. "Can't wait to see all the performances!"
