The WB's beachy hit ''Summerland'' features more than its share of bikini-bared skin. But with best friends Ava (Lori Loughlin, above left) and Susannah (Merrin Dungey) starting their own clothing label -- while raising Ava's suddenly orphaned niece and nephews -- chic fashions play a key role. Here are some of the items we're summer lovin':
1 OH, CARRIE Stylish careers mean glam outfits. A recent episode featured a fashion show of Ava's trendy designs, which ''Summerland'' costume designer Roberta Haze calls ''clubby and 'Sex and the City'-ish.''
2 HI LO COUNTRY Haze throws together surfer gear and high fashion, mixing boutique finds with staples from chains like Urban Outfitters. She loves the one-of-a-kind designs made from vintage fabric at Principessa in Venice, Calif. The look is just as popular off screen. Says Dungey, ''I should just sign my paycheck over to Principessa.''
3 THE RIGHT TO CHOOS ''I do a lot of flip-flops,'' says Haze of the thongs sported by the gals in the cast. ''But when the episode calls for it, I do Jimmy Choos.''
