One-stop shopping? Bor-ing. For us, the hunt is part of the thrill.But all that is going to change with tomorrow’s opening of Sa Va.Designer Sarah Van Aken’s new bright white Rittenhouse outpost holds her complete collection of locally produced clothing for work, play, and just hanging around. (Check the hangtag for exactly what sustainable parameters each garment meets.)Styles are divided into four sections: workday (conservative basics with expert tailoring and interesting detail), night out (sexy draped tops, dresses in unusual finishes and luxurious fabrics), Saturday (items with a laid-back vibe and an emphasis on fit), and Ça Va (current inspiration pieces). So you can get all the basics covered, as well as handbags by Helena de Natalio, Zina Eva, and JPK; Van Aken’s jewelry; and additional lines like Double Happiness, Presh, and Style Naturale.Leaving more time to enjoy the thrill of credit card debt.Sa Va, 1700 Sansom Street (215-587-0004 or savafashion.com).
