Super comfy, stays put!

I ordered this from Backcountry.com (awesome service!!!) and it is so comfortable I had to get a few more. I got Capri Blue Flower and it's kinda wild but it matches just about everything in my closet--for wearing around town in warm weather or for yoga. It stays put in yoga class so I'm not tugging at straps, re-adjusting, or pulling back down over tummy. It stays put but is not tight...I can't figure out the mechanics of it when it feels a little swishy on but doesn't go anywhere either! Love it!!!
