Grammys 2013: Best and worst dressed

Florence Welch is the night’s fashion winner so far, paying homage perhaps to the year of the snake in a poison green sequin gown by Riccardo Tisci for Givenchy. With reptilian 3-D stud-like details, the long sleeve style is stunningly unique. It should be, it was made especially for her, and the color rocks with her red hair.

Fashion Critic Booth Moore’s picks for best and worst dressed at the 55th Grammy Awards.

The always well-behaved Taylor Swift played the goddess in a strappy chiffon pleated gown with metallic embroidered straps by J. Mendel with cutouts over the waist. (Kirk McKoy / Los Angeles Times; Christopher Polk / Getty Images)

And then along came Ashanti in a Tony Ward Couture gown. The embroidered black lace may have looked innocent enough, but that keyhole of cleavage and slit to the hip were pushing the bounds -- in terms of propriety, yes, but mostly taste. (Kirk McKoy / Los Angeles Times; Mike Nelson / EPA)

Janelle Monae worked her signature androgynous look in a tux jacket with sparkly lapels, a dripping bow tie and a flat top hat. She told E!, “I’m wearing ideas,” and credited her stylist Erin Hirsh for putting it all together. (Kirk McKoy / Los Angeles Times; Frederic J. Brown / Getty Images)

Jennifer Lopez in Anthony Vaccarello. She took the stage to give out the first award of the Grammys, struck a pose and noted that she “got the memo” about the dress code. (Kirk McKoy / Los Angeles Times; Mike Nelson / EPA)

And Kelly Rowland is a vision in a black Georges Chakra gown with geometric mesh panels down the front and sides. A fashion daredevil, god love her. (Jordan Strauss / Invision / AP)

Beyoncé shocked us all not with deep décolletage, but by wearing a graphic black and white crepe jumpsuit by Osman Studio that played into the season’s 1960s Op Art fashion trend. (EPA / Los Angeles Times)

There is nothing sexier than Rihanna in that red-hot gown by fashion insider favorite Azzedine Alaia. At first glance, the cross-front style didn’t seem to reveal too much. But upon further inspection, the gossamer-like fabric hinted at everything. With Rihanna’s soft, wavy hairstyle and minimal makeup, it was perfection. ( Jason Merritt / Getty Images)
