L7 Merch & Design, 21310 Sunnydale St, Saint Clair Shores, MI 48081, US

St. Clair Shores resident Milissa Tischbein opened Secret Treasures Upscale Resale two years ago. Located on Harper Avenue, the store's bright-green and polka-dotted sign is hard to miss. The funky vibe continues inside where music plays overhead and different displays highlight a wide variety of items, such as shoes and purses. Racks full of children's, teen's and women's clothes are set up throughout the store. The shop accepts updated and vintage clothes, just call to schedule a buying appointment.
