Owners Selling Bismarck’s Mainstream Boutique After 15 Years

Bismarck's Mainstream Boutique, the women's fashion brand at 4816 Ottawa St is now officially for sale, according to a post on the store's Facebook page.

The boutique moved from its longtime downtown Bismarck location, near Liberty Tax off of Bismarck Expressway, to the North end of town in July 2026.

That old downtown storefront didn't stay empty long - Vacuum moved in shortly after Mainstream's relocation.

The current owners have been running the Bismarck business for 15 years, but now they are ushering in a new era and are ready to hand over the reins to someone new.

We are excited to find someone who shares the same passion for fashion, community, and making every customer feel special, and who will continue the Mainstream Boutique ritual.

For now, it's business as usual - the boutique is still open and selling the latest fashions and styles to the people of Bismarck. If you have a passion for fashion and have ever daydreamed about running your own boutique, this is about as turnkey as it gets. If you're interested in buying and ready for a new opportunity, contact the owners through Facebook or call the store at 701-751-0203.
