How Southern Marsh fits

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.
