Lululemon has a store for tween girls that is taking over retail

Lululemon is a stalwart when it comes to the athleisure movement - it's wildly popular. So naturally, we can assume that kids want to dress like their moms who wear it, right?

After all, kids have their own Uggs, their own Burberry, and their own J. Crew - why shouldn't they have their own their own Lululemon?

Enter Ivivva, which was founded in 2009 and takes Lululemon's yogic platitudes and apparel, shrinks them, and adds a dose of glitter.

There's currently a pop up shop going on in Union Square in New York City, so we took a look to see what it's like inside one of the stores. (Don't worry, we didn't look weird - I'm short and can fit into a 12 or 14 at Ivivva.)
