PHILADELPHIA (WPVI) — What began as a four-piece athleisure collection launched from a Philadelphia home has grown into a national apparel brand shipping to all 50 states.
Addison Bay, founded by Marguerite Adzick in 2018, now releases about 20 collections a year and operates from its Market Street headquarters, where design, shipping, and other operations happen under one roof.
“OK, so I started Addison Bay back in 2018,” Adzick said. “Walking around Rittenhouse Square and seeing everyone in activewear. So far beyond the gym, running errands, school drop-offs, restaurants, even. And I was like, there is a movement happening,” she said.
Adzick developed the business plan at home on Addison Street, which inspired the company’s name.
The original collection consisted of four styles, including what remains the brand’s signature product.
“The everyday legging, which still exists today, it’s kind of like our signature thing,” Adzick said. “It has that like fashion-forward, stylish element, but it’s still something that you can wear every day. It has the iconic six stripes on one leg.”
The company’s latest growth came through a partnership with the Philadelphia Eagles, which Adzick described as a major milestone.
“Absolutely. Such a pinch-me moment,” she said. “But also it’s just one of those things. It’s like the team has been working so hard for so many years and for people to notice, like the Philadelphia Eagles, hey, I want to partner with that brand. It just was such a cool feeling.”
According to the company, one of the items in the Eagles collection sold out in 20 minutes after launch.
Addison Bay’s designs are planned about a year in advance, and many product names pay tribute to Philadelphia streets.
The brand now operates stores from Suburban Square to Naples and sells through retailers, including Dillard’s.
“Pennsylvania and really Philadelphia specifically has shown up for us since day one,” Adzick said. “Like, truly, I feel like we survived and thrived because of our consumers in Philly really supporting us from day one. Eight years later, we just opened our fourth store in Dallas, Texas, and we’ve shipped to all 50 states, but it all started in Philly.”
