About Us

Fiancee Bismarck began as a high school entrepreneurship project of the stores now owner, Kinzey. After her senior year Kinzey opened and managed Fiancee Bismarck for 9 years. In November of 2016 Kinzey and her husband Aaron officially purchased the store from the previous owner. In the year 2017 Fiancee Bismarck will be rebranding to the name KooKoo’s Nest. We will still offer the same amazing customer service and exquisite prom gowns and tuxedos as always.

We carry designs from Sherri Hill, La Femme, Clarisse, Mori, and more. We have recently expanded our brand to become one of Bismarck’s most affordable specialty clothing boutique's that provides juniors and women's ready-to-wear clothing and accessories.

At Fiancee Bismarck/KooKoo’s Nest we pride ourselves on being a small business that works to enhance our community and downtown. We value the relationships we create with our loyal customers and our fabulous designers.

We adore each and every customer that sets foot into our shop. It is such an honor to help dress you for some of your biggest milestones in your life.
