Where Style Finds Its Second Story

Located in downtown Auburn Hills, Michigan, Theory & Thread is a women’s and teen consignment boutique offering a curated mix of designer resale clothing, accessories, and unique fashion finds.

For over 25 years, our founder, Thayer, has been curating wardrobes for herself, her daughters, and friends - always searching for pieces that combine quality, style, and individuality. After a major career pivot (and one honest heart-to-heart conversation about what she truly loved doing), the answer became clear:

Open a store that makes fashion feel good again.
Theory & Thread was created from a love of fashion and a passion for doing good.

Our guiding belief is simple: Look Good • Feel Good • Do Good
When you look good, you feel good. And when you feel good, you do good.

We’re more than just another resale and consignment shop—we’re a community boutique where women and teens can shop amazing styles, enjoy the experience, and know they’re supporting sustainable fashion. Every purchase helps keep quality clothing in circulation and out of landfills—because style shouldn’t come at the planet’s expense.

Whether you’re shopping, consigning, or discovering your next favorite piece, we invite you to stop by, bring your friends and make a day of it.
