Las Vegas--Grammy-nominated group the Goo-Goo Dolls took the stage Thursday night on the Wynn Las Vegas’ Sunset Pool Deck for the official opening night party of Couture 2011.

The group, which first rose to fame in the mid-1990s, entertained the crowd with chart-topping hits including “Name,” a song from the 1995 album “A Boy Named Goo” that turned into the band’s first big single, as well as “Slide” and “Broadway,” both from the 1998 album “Dizzy Up the Girl.”

Party attendees ate, drank and danced pool-side while listening to the Dolls on a breezy Las Vegas night. The group, which formed in Buffalo, N.Y., in 1986, released its ninth studio album, “Something for the Rest of Us” last year.

The opening night party kicked off at 7 p.m. at the conclusion of Couture’s first day.

This year, the show features a new show floor design and, according to Couture organizers, exhibitors are up 15 percent as compared to last year.

This increase led to a surge in buyer attendance on the first day, and buyers and exhibitors alike were upbeat amid the buzz on the show floor.

“Couture is a very civilized and elegant show. It’s the perfect balance of luxury and fabulous presentation,” Gerard Riveron, general manager of Dorfman in Boston, said. “It’s all about creativity at Couture. We discover new ideas every year we come to the show, and we love to be here.”

Couture runs through Monday, June 6 at the Wynn. For more information, visit www.TheCoutureShow.com.
