and we make high-quality, year-round knitwear in sizes XS-XXL. Because you should have a favorite sweater for every season.

Knitwear is all we do,

so we’re like, really good at it. We choose our materials with care—focusing on natural, long-lasting fibers like cotton, cellulose (🌱) fibers, and synthetic yarns when needed for function and wear. While we’re big on comfort, we’re even bigger on fashion that doesn't feel disposable.

Machine washable and easy to care for, your favorite Callahan pieces are made to live in your closet season after season.

Using a process called fully fashioned knitting,

our styles are ethically manufactured and made to shape at a small, women-owned facility in Shanghai, China, with no scraps and less waste.

Michelle’s love for design

started at a young age with a hot glue gun, her mom’s sewing machine, and a halter top. “I always wanted my own apparel line,” she says, “as long as I can remember.”  

After a degree in apparel design and textiles, Michelle started her career in fashion as a buyer. She officially launched Callahan in 2013—now stocked everywhere from small boutiques to Revolve and Anthropologie. Michelle lives in Los Angeles with her two cats.

Woman-owned, women-run,

and inspired by the ones who just get it—the ones who are effortless but intentional, and know a good knit when they feel one. Born in California, our knits carry that same energy: unique, timeless and always ready for whatever comes next.
