Authentic product purchased from zumba.com. This popular item was released yesterday and immediately sold out! It's the latest release, from October! It's green, which is unusual for ZUMBA! Green is also great for Christmas! ZUMBA's free size is large, so it's good for alterations like cutting. It's from the official website, so you can be assured of its authenticity. Please feel free to use it if you'd like.
