About Us

Welcome to Harper & Co., your go-to boutique for trendy, size-inclusive women’s clothing. Based in small-town Iowa with a big love for fashion, Harper & Co. was founded by Jillian Heisdorffer, a lifelong style lover with a passion for helping women feel confident and beautiful in what they wear.

Jillian started Harper & Co. with a simple goal: to create a space where women of all ages, shapes, and sizes can shop pieces that truly make them feel good. Her eye for flattering fits, on-trend styles, and everyday comfort guides every collection—from bestselling staples to seasonal favorites and the graphic tees customers can’t get enough of.

Whether you're browsing online at harpercoia.com or following along on Instagram at @harperco1839, Jillian is dedicated to bringing you a friendly, personal shopping experience, fast shipping, and styles that make getting dressed the best part of your day.

At Harper & Co., it’s more than clothing—it’s confidence, community, and celebrating who you are.
