Florida Georgia Line‘s Brian Kelley and his wife Brittney are ready to introduce their new fashion line to the world and they’re starting with the country fans that have descended on Nashville for the CMA Music Festival.

Tribe Kelley made its Nashville debut in an extremely limited engagement – it was open for four hours only – in the Lucchese boot shop on Thursday, the first day of the annual festival.

“We thought it would be fun to kick this off while the fans were in town,” Brittney told PEOPLE. “Brian always wears Lucchese boots, this is such a beautiful store and really suits the natural, earthy look of our line. They were so nice to let us do this.”

The line includes women’s soft jerseys and tees, poly-suede bell bottom pants, shirts, caps and some jewelry pieces. Brittney and Brian, who donned a cap and a shirt from their upcoming men’s line Sleep With Wolves, were joined by Brian’s bandmate Tyler Hubbard and his fiancée Haley Stommel.

Tribe Kelley was born on a dinner date when Brittney sketched out an idea for a shirt on the tablecloth. “I gave it to our graphic designer and she finished it up and that’s when it all started to come together,” Brittney said of their very first item, a jersey shirt with a teepee and the words “Tribe Kelley Motel Nomads Welcome.”

“It was so exciting!” she said. “I thought, ‘This can really happen. The ideas we talk about and draw can take a physical form.’ It’s like his ideas that become songs that creative process.”

Brian and Brittney are also collaborating with The Giving Keys, a Los Angeles based non-profit that employs people transitioning out of homelessness to make jewelry out of repurposed keys. “We love what they do and we’re working with them to create a Tribe Key,” said Brian.

The name of the line seemed only natural, explained Brittney. “Brian and I feel like when we got married, we formed a tribe, we started our tribe. I have Native American ancestors and Haley and Tyler got us a teepee the night before we got married for our wedding gift, so it all came together. We are Tribe Kelly!”

Though they intend to do future pop-up stores, for now Tribe Kelley – which will introduce summer items later this month – is available online.
