Brand profile
Founder-run Baton Rouge label making Southern-lifestyle basics — duck-logo graphic tees, polos, oxfords and quarter-zips — for men, women and kids.
16 brands like Southern Marsh like Southern Tide, Vineyard Vines, Polo Ralph Lauren →

The flying-duck logo on cotton and Seawash graphic tees is the core product; polos, oxfords, quarter-zips, shorts and swim trunks fill out the range.
Started in 2008 by two LSU students in Baton Rouge, it sells through its own site, four stores and independent boutiques and campus shops across the South.
Still privately held and founder-run, the brand ships over a million pieces a year of men's, women's and youth casualwear in the lower-mid price range.
Overall fit
runs large
Southern Marsh cuts in the traditional Southern-prep style, so tees, polos and pullovers typically feel roomier and boxier than modern slim-fit brands, with many buyers reporting they could have gone a size smaller.
Tip: Most shoppers do best sizing down one from their usual tee/pullover size unless they want a loose, tucked-in Southern-prep look.

By category
| Category | Runs | Shape | Size advice |
|---|---|---|---|
| Hoodies & sweatshirts | runs large | roomy, casual pullover shape built for layering over a polo or oxford | Quarter-zips and hooded pullovers are widely described as oversized, so sizing down usually gives a cleaner fit. |
| Shirts & overshirts | slightly large | classic fit oxfords and polos with a fuller chest and waist, not tapered | Order your normal size for a traditional look, or drop a size if you prefer the shirt closer to the body. |
| T-shirts & graphic tees | runs large | relaxed, straight-cut body with a slightly wide chest and sleeve | Size down for a modern fit; keep your usual size if you like a loose tee or expect a bit of shrinkage from the garment-dyed Seawash styles. |
