For the past two decades, the Yeah Yeah Yeahs frontwoman Karen O, has defined her rock star style with some help from a self-taught fashion designer known as Ms. Joy.

The first piece Ms. Joy ever created for Karen O was a deconstructed prom dress embellished with plastic flowers and white paint that read, “Yeah Yeah Yeahs” across the front.

According to a story from the New York Times Ms. Joy said that she only had one night to make it and began by shredding up a secondhand blue-satin prom dress. Ms. Joy laughed as she said, “It was hideous.”

Karen O, on the other hand, remembered the look very differently, saying that she hoped she could live up to the look while on stage.

Since then, Ms. Joy has designed countless looks for Karen O, including a blue spandex leotard with silver peplum that Karen O wore on the cover of the June 2004 issue of Spin, the tailored yellow suit that Karen O wore while performing at the 2013 Latitude Festival in Southwold, England and many of Karen O’s latest “Cool It Down” tour looks.

Katie Baron, the author of “Fashion + Music: Fashion Creatives Shaping Pop Culture,” has compared Karen O’s relationship with Ms. Joy to that of David Bowie’s relationship with designer, Kansai Yamamoto, who created many of Bowie’s iconic looks.

Karen O said in an interview with the New York Times that when she went to Ms. Joy with the costume ideas for the “Cool It Down” tour wardrobe she wanted the looks to be inspired by “‘70s rock glam.”

One of Ms. Joy’s latest pieces created for Karen O was a kaleidoscope bodysuit, trimmed with primary-colored tape. Karen O said the look was on the verge of being “tomboyish” and had a more DIY feel, something Karen O said she preferred to a runway wardrobe.

Karen O deputed the look at the start of the “Cool It Down” tour at The Anthem on May 3 in Washington D.C.

One of Karen O’s staples on any tour is to incorporate a piece of clothing labeled with her initials and in Washington D.C., while wearing one of Ms. Joy’s many “Cool It Down” costumes, Karen O added a bedazzled “KO” across the front of the jumpsuit.

If there is anything that defines the “Cool It Down” tour it is a statement glove. One of the photos used to promote the album and the tour was a photo of Karen O holding up a microphone while wearing a metallic pink glove layered with a silver bangle.

And the gloves didn’t end there, throughout the tour, Karen O wore many gloves but one that continued to reappear was a pair of glittery, red gloves with long strands of fringe hanging down from them.

While in Houston, Texas, Karen O wore the iconic pink glove, along with an orange, pink and blue striped outfit featuring leather accents. The look, although not as extravagant as some of the jumpsuits, continued to reflect Karen O’s “‘70s glam rock” theme.

Pasadena, CA

One of the Yeah Yeah Yeahs stops on the tour was in Pasadena, California, headlining the Just Like Heaven Music Festival where Karen O wore a red, shoulderless jumpsuit embellished with glitter and fingerless gloves.

Chicago, IL

After having to cancel their stop at the Boston Calling Music Festival due to Karen O coming down with a bad illness, the Yeah Yeah Yeahs returned to their tour in Chicago. Karen O wrote to fans on social media after the show saying, “Thank you for bringing me back from the dead Chicago.”

Another one of Ms. Joy’s designs for the “Cool It Down” tour was a multicolored studded jumpsuit complete with red tinseled opera gloves and a glittering red, black and blue cape featuring a sunburst design.

Seattle, WA

One of the last stops of the “Cool It Down” tour, in Seattle, Washington, was marked by Karen O’s colorful headpiece. The piece, resembling a sunburst, featured many of the colors used throughout the tour and matched the iconic pink glove used throughout the tour.

Portland, OR

In Portland, Oregon, Karen O wore another bedazzled jumpsuit that fit the label of “‘70s glam rock.” The jumpsuit featured blue, yellow and red glitter designs and had oversized sleeves, a look that resembled many of David Bowie’s iconic ‘70s jumpsuits.
