Though it’s tucked into a tiny storefront far from San Francisco’s well-traveled Union Square retail district, Department Seventeen (shop.dept17.com) has hooked customers worldwide with its hip menswear and handsome accessories. The 250-square-foot Russian Hill boutique draws shoppers and online orders from as far away as Sweden and Australia by offering polished looks with a playful streetwear sensibility.

Now, the three young men behind Department Seventeen have also launched an eponymous line of smartly cut shirts, scarves, neckties and pocket squares made in San Francisco — and, though none of the founders has a formal fashion background, the venture is thriving. Check out the brand’s new Western-style chambray button-downs debuting this season (detailed shoulder stitching adds a splash of character), and look your best with fall fashion advice from Department Seventeen co-founder Nelson Jang.
