I'm actually sortof a regular there. I can say without hesitation that it is one of the coolest stores I've ever been to in my life, competing with Sid Mashburn in Atlanta. They are in an up-and-coming area of Nashville (hardly out in the country) and they seem to be doing an excellent business. They are located in a converted service station (hence the garage door) and the backyard has been converted into a really cool venue. During the spring, summer, and fall they host a "Supper and a Song" once a week where they have a singer-songwriter or a group come and play a free concert and the local artisan taco truck pulls up and serves dinner. Microbrews are copious and whiskey is a frequent guest on colder nights, most memorably at their recent retrospective of photographer Jim McGuire's work with musical guests Justin Townes Earle and Holly Williams.
The store sells a mix of their own products (denim, modified vintage t-shirts and sweatshirts, scarves); new products from other brands (RRL, Rogan, J Brand, Billykirk, White's); and an exquisitely-curated vintage collection (hundreds of boots, Levis, hats, wool sweaters, flannel). All of their denim is made in-house, half of the shop is a huge workshop full of vintage sewing machines, and paper patterns hang from the ceiling. There are rows and rows of coffee cans filled with every rivet, button, etc. you could imagine.
The owners, Matt and Carrie, are great folks who really really know their stuff and have fantastic taste. Their employees are very stylish and helpful. I've never been in there that they didn't have a number of customers purchasing stuff, and while I've never bought any jeans there, I have lusted after them. I cannot recommend this place highly enough.
