Mason Jar Boutique is an affordable online clothing boutique selling the latest trends. We started in 2014 and have been growing quickly! Our warehouse is located in Sioux Falls, SD and we have three retail stores: Sioux Falls, SD + Fargo, ND and Cave Creek, AZ.

So who are we? We are two sisters that grew up in Arizona together and had (lots) of sibling love. We have now grown up and each has spent our time apart. It’s amazing how you really start to appreciate one another with 2000 miles and 13 kids in between you. So what did we decided would be the solution?! Working together of course.


(Ashley here) Let's take a second to introduce ourselves. Hello! I’m Ashley and I'm the older, smarter, and easy-going sister. I have 10 kids and live in Scottsdale, Arizona. My life is spent running my kids to all their crazy activities, all while I try to maintain my passions of running, yoga, and an occasional triathlon. My style needs to be quick, cute and (NOT hand) washable. My accessories tend to be a fuel band and a hair tie. But that does not mean I don’t love a cute sundress and a fun outfit for a girl’s night out. I’m sure you will be able to find all of those things right here.


Now for my younger sister, Katie, she is my crazy, intense fashion fanatic who is always ready for a new adventure. When she has something in her head it happens. She is the mover and shaker of this twosome, from cheering at ASU to being a mom of 3, running the boutique and running her three girls to all the gymnastics and cheer meets. She makes things happen. She has effortless style and is always on point. She is of course the main style guru.


As you can tell we are opposites but together we are ready to help you come up with your own style and outfits. This is the place for you if you’re laid back or ready to shine! Thank you for making MJ what it is today after more than 10 years of being in business!
