ABC/Eric McCandlessTonight, Little Big Town trades in four-part harmony for fashion, as the “Girl Crush” hitmakers guest star on Project Runway All Stars. In the new episode, the CMA Vocal Group of the Year challenges the contestants to create “opposites attract” looks they could wear to the Academy of Country Music Awards in April.

Judging from their past red carpet looks, the members of Little Big Town are no slouches in the fashion arena — though one member of the band does have some particular expertise. Karen has her own line of clothes called Fair Child by Karen Fairchild, available online.

“We’re just getting started, so a lot of it’s like dramatic pieces — things that I would wear onstage, things that I love, and things that are easy to wear,” she says.

The singer, who just had a chart-topping hit with tour mate Luke Bryan on “Home Alone Tonight,” admits her tastes may be a little more fashion-forward than some folks’, though.

“I would wear fringe to Target when I go shopping,” she admits. “You do wear fringe to Target!” Kimberly Schlapman interjects, as the band erupts into laughter. “Or to the grocery store,” Karen admits. “So yeah! Lots of little fringe-y bits, faux fur, faux leather, at a good price point for the fans.”

You can see what Karen and the other members of LBT think of the looks the contestants come up with in the episode called “A Little Bit Country, A Little Bit Rock N Roll,” tonight at 9 p.m. ET on Lifetime.
