Answer by taking a quote from the following article:

Limp Bizkit is an American rap rock band from Jacksonville, Florida, formed in 1994. Their lineup consists of Fred Durst (lead vocals), Sam Rivers (bass, backing vocals), John Otto (drums, percussion), and Wes Borland (guitars, backing vocals). Their music is marked by Durst's angry vocal delivery and Borland's sonic experimentation. Borland's elaborate visual appearance, which includes face and body paint, masks and uniforms, also plays a large role in the band's elaborate live shows.

Borland is known for performing in costumes and body paint during concerts, appearing in bunny and kung fu suits, and painted as a skeleton and what he describes as a "burnt match". Describing the character, he stated, "I go onstage wearing almost nothing. I have underwear and my boots on, and I paint my whole head black--from the neck up--and I have the black contacts. All you can see is these glowing teeth." Borland's black contacts were customized for him by a company noted for making contacts for the science fiction TV series Babylon 5.  In addition to Borland's visual appearance, the band has also used elaborate stage setups in their performances. Their Ladies Night in Cambodia club tour visually paid tribute to the film Apocalypse Now, with an elaborate stage setup which featured an empty Jeep, camouflage mesh and palm trees. During the band's tour with Primus, Limp Bizkit took inspiration from Primus' trademark self-deprecatory slogan "Primus sucks": Durst, Borland, Rivers, Otto and Lethal took the stage with middle fingers raised. According to Borland, "they finger us back--and you know what that means to us--that they love us. It's kind of like saying something is bad when you really mean good. Les Claypool came out the first night of the tour and got a big kick out of it. We figured it was the right idea. It makes hecklers go 'huh.'"  During the band's sets at Ozzfest, audience members at the tour heckled Limp Bizkit, leading the band to use a 30-foot toilet as a stage prop, which they would emerge from during each performance; the band punctuated their sets by "flushing" cardboard cutouts of pop stars like Hanson and the Spice Girls. During their appearance at the first Family Values Tour, Limp Bizkit performed on a set which the Los Angeles Times described as "a mix of The War Of The Worlds and Mars Attacks". The band emerged from a spaceship during the tour, and Borland continued to experiment with visual appearances. During the band's Halloween performance on the tour, each of the band's members dressed as Elvis Presley at various stages in his career.

Do they use costumes often?
continued to experiment with visual appearances.
