About Posh Boutique


Posh Boutique first opened its doors in 2007 and has since been a go-to shopping destination for women of all ages. We offer brands that are not easily available in the Sioux Falls area and our premium denim is a staple for many. AG, Seven for All Mankind, Hudson, Paige and Joe's are some of our favorite denim brands. While we love our jeans, let’s not forget the many tops, dresses and accessories we carry for all occasions and budgets.


In February 2018, Alyssa Nix bought Posh Boutique from its original owners. Born and raised in Sioux Falls, Alyssa developed a love for fashion at a young age and decided to dedicate her educational and professional career to helping those around her look and feel their best. After attending college in Boston and graduating with a Bachelors in Fashion & Retail Management, she worked to develop her skills and expand her knowledge of the industry.


Upon returning to Sioux Falls in 2016, Alyssa started a freelance visual merchandising business, Visuals by Nix. That business opened many doors and eventually led her to take over the very boutique she had shopped at since it opened a decade prior.


Our mission at Posh is to help women feel empowered and confident by supplying high quality clothing that fits their lifestyle and personality. We carry sizes XS-3X and we have something that is appropriate for any age. Alyssa personally selects every item in that comes into the store and we don't sell anything she doesn't stand behind. The best part? Over half of our products were made in the U.S.A.
