South Moon Under began in 1968, when Frank Gunion opened a surf shop in Ocean City, Maryland, stocked with boards, screen-printed tees and swimwear. That beach-town beginning still shows in the coastal mix: South Moon Under is now a stylish everyday retailer for women's and men's clothing, swim and resort wear, denim, occasion dresses, shoes, bags, jewelry and loungewear. Its assortment brings together labels such as Paige, Rails, Farm Rio, AGOLDE and L*Space, alongside new arrivals that rotate through stores and the online shop. For shoppers comparing South Moon Under sale finds or looking for a South Moon Under promo code, it helps to think in terms of a full outfit, from swim to dinner layers. Phia can compare South Moon Under prices, test coupon codes at checkout and look for secondhand or resale prices on pieces worth keeping.
