The law has spoken: leggings are not pants and the sidewalks of New York are not your yoga mat. So toss out the athleisure wear and take advantage of these two shopping opportunities. 

unnamed (15)The Vintage Twin NYC Pop-Up Shop
July 22 to 29 at 42B W. 14th St., Union Square
Morgan and Samantha Elias, the titular twins who operate this roving vintage shop, usually pop up in the slim space at 355A Bowery, but this time they’re slipping into something a little more comfortable. “It’s going to look like we took over a vacated Gap store,” Morgan promises of their larger space on West 14th Street. But don’t expect plain-Jane, off-the-rack designs: The Eliases buy ’60s-to-’90s pieces from estate sales and then adapt them by, say, turning a gown into a short skirt, or sewing a section of Teenage Mutant Ninja Turtles bedsheets onto a denim jacket. Plus, we’re told a “jean-ius” will be on hand at a “denim bar” to size each customer for the perfect fit of Levi 501s or Wranglers.

Bang Tidy Pop-Up Market
July 23 and August 6 and 20, 5pm to 10pm at Diviera Drive, 131 Berry St., Williamsburg
What’s Diviera Drive doing with its sprawling patio other than parking a boat in it? The Williamsburg restaurant and dance den is now hosting a summer bazaar put on by Bang Tidy, an art-music-shopping endeavor that, in the past, has invited stylish such-and-suches and local designers to clean out their closets and their inventory at places like Output and the Cannes Film Festival. Past vendors have included Room 305, Brooklyn designer Angela Dimoff, and others. Among those who’ll be hawking this week is jeweler Louise Manna, and there’ll be art for sale, too. A DJ will make sure that that you dance and shop till you drop.
