Whooshing back the dressing room curtain, DeWanda Wise emerged in a red-and-white-striped bandeau top and matching wide-legged pants — a circus clown’s idea of resort wear. “Eighty-nine percent of my style choices are like, ‘Can I get away with this?’” Ms. Wise said, laughing. She decided that she could.

Nola Darling, the polyamorous character Ms. Wise plays on “She’s Gotta Have It,” now in its second season on Netflix, gets away with a lot, too.

During filming, Ms. Wise, 35, doesn’t have time to shop. But with the season wrapped, she was spending a cloudy afternoon at City Opera Thrift Shop, a charity store near Gramercy Park in Manhattan that she discovered as an undergrad at New York University.

A lot of Nola’s outfits come from thrift stores and the like. A lot of Ms. Wise’s do, too. At City Opera, a handsome shop with a mezzanine framed by wrought-iron balustrades, she had arrived in a black crisscross jumpsuit embellished with gold buttons. She had snagged it at a North Carolina flea market, then altered it to fit like a very snug glove.
