Southern Marsh
Re-checked daily
Founded in 2007 by Matthew Valiollahi and Stephen Smith, Southern Marsh Collection is an American clothing and accessories label out of Baton Rouge, Louisiana, built to represent Southern culture.

The two founders were students at Louisiana State University when Matthew, a senior, approached his friend Stephen to design the brand — out of which came the trademark mallard logo and the company's whole aesthetic. They began by selling their designs, then moved into engineering fabrics from the ground up, with adjunct professor Walter Morales helping refine the business plan.

From a T-shirt start, the line grew into shirts, shorts, outerwear, hats and accessories, sold through more than 700 retailers across the United States. The company landed at #689 on Inc. Magazine's 5,000 fastest-growing list in 2015 and opened its first store in The Woodlands, Texas, in 2018.

Southern Marsh shopping FAQ

Is Southern Marsh worth it?+

If you like easy, Southern-inspired prep, it tends to land well. Southern Marsh is an American clothing and accessories brand whose pieces aim to represent Southern culture, spanning shirts, shorts, pants, outerwear and accessories. Value really comes down to taste: it is approachable lifestyle apparel built around a clear aesthetic rather than a high-fashion label.

What is Southern Marsh known for?+

Southern Marsh Collection is an American clothing and accessories retailer that markets a variety of shirts, shorts, pants, outerwear and accessories designed to represent Southern culture. Its identity is tied to that Southern-style lifestyle look, anchored by the brand's trademark mallard logo.

What does the Southern Marsh mallard logo mean?+

The mallard is the brand's trademark logo, created early on by co-founder Stephen Smith when he was asked to design the brand. It came to define the general aesthetic of the company and signals its Southern, outdoors-leaning sensibility.

Who founded Southern Marsh and when?+

Southern Marsh was founded in 2007 by Matthew Valiollahi and Stephen Smith, both students at Louisiana State University at the time. As a senior, Matthew approached his friend Stephen to design the brand, from which came the trademark mallard logo and the company's overall look.

Where is Southern Marsh based?+

The brand is headquartered in Baton Rouge, Louisiana. Its Louisiana roots, going back to two LSU students, are central to the Southern culture it sets out to represent.

Did Southern Marsh always make more than T-shirts?+

No, it started small. Originally the brand sold only T-shirts, then expanded as it grew. Today it markets a much wider range including shorts, pants, dress shirts, jackets, pullovers, polos, bags, performance clothing and hats.

Where can I buy Southern Marsh?+

Southern Marsh partners with over 700 retailers across the United States and also sells to online shoppers. Its first brick-and-mortar store opened in October 2018 at Market Street in The Woodlands, Texas, so you can shop it in person, online, or through its many retail partners.

How did two college students turn Southern Marsh into a real business?+

After founders Matthew Valiollahi and Stephen Smith began by selling their designs in 2007, they moved into designing fabrics from the ground up. Walter Morales, then an adjunct professor at LSU, helped the pair refine their business plan as the brand found its footing.

Has Southern Marsh grown quickly as a company?+

Yes. Its product line expanded significantly after 2007, driven largely by sizable revenue growth, and in August 2015 the company was listed at #689 on Inc. Magazine's 5,000 fastest-growing companies in America. That growth funded its move beyond T-shirts into a full apparel range.

How should I wash Southern Marsh shirts to keep them looking good?+

As with most casual cotton-leaning prep apparel, gentle care helps: wash in cooler water, avoid harsh bleaching agents, and air-dry or tumble on low to protect the print and fabric. Following the garment's own care label is the safest way to keep a Southern Marsh shirt looking fresh wear after wear.

Does Southern Marsh make college apparel?+

Yes. Alongside its core lifestyle range, the company manufactures licensed college apparel, fitting naturally with its roots as a brand founded by two LSU students. That collegiate connection is part of its Southern, campus-friendly appeal.
