Pop into Magdalena Trever's Lower East Side shop, and you’ll find a Beach Blanket Bingo-meets-Project Runway vibe. And since the space doubles as Trever’s studio, you can also check out her design process. “I want customers to experience the entire creation process and witness my inspiration,” Trever says. Her knit suits start around $225; the shop also offers vintage sterling silver and 10–18k gold-plated rings and wristwatches ($21–$180). You’ll find knit dresses and sweaters ($55 and up) for covering up by the pool.
