The tide is high for nautical-themed threads at Seaton, the latest boutique on Melrose from well-known L.A. retailer Jill Roberts and her husband, Mark Freeman. Seaton sells the California dream - 'sun, surf, fun!' in the form of its namesake line of stylish cotton tops, sweats and sundresses (often emblazoned with the store's mascot, the seahorse) and luxurious, ultrasoft cashmere hoodies and wraps. Other seaside must-haves for beach bunnies, surfer dudes and their tykes (the store has duds for men and children, too) include Eres bikinis, J Brand jeans, Havaianas flip-flops and Hunter Wellies, as well as beach towels and Savon de Marseille soaps.
