Don't Miss:

Stars showed up in pretty summer-ready colors at the 2012 Billboard Music Awards last night, held at the MGM Grand Garden Arena is Las Vegas. Katy Perry matched her iridescent lilac Blumarine design to her plum highlights, Taylor Swift took home the event’s Woman of the Year award in a strawberry red lace Elie Saab gown, Carrie Underwood turned up the volume in a frothy slate blue and rose tulle Oscar de la Renta creation, and Miley Cyrus took the plunge in double-breasted Jean Paul Gaultier tuxedo mini dress. See what everyone else wore to the awards show by clicking through the gallery! Then, tell us: Who do you think looked best?

Finally, your gym-time staple is getting a chic boost! Seen on celebrities such as Beyonce, Rashida Jones, Kate Bosworth and Miranda Kerr, wedge sneakers are Hollywood’s favorite new footwear. The hybrid is both fashionable and functional, with chunky heels built into the sporty look. Pair them with leather leggings or a chiffon skirt for a polished finish. See a few of our favorites in the gallery, and tell us, would you wear this style?

Polka dots are spot-on this spring! Diane Kruger paired her dots with another major red carpet trend: color-blocking, Krysten Ritter picked an oversize version of the pattern in a flirty ’50s shape, Gwen Stefani sweetened up her tough girl leather jacket and jeans with dotted denim, and Heidi Klum lent some sexiness to the style with a gutsy hemline and spiked heels. See how more celebrities wear dots, and find out where to shop their looks, in the gallery.
