I noticed that there are two for sale, and they are quite similar, but the one she was actually wearing in the show says "blue" in the description and is about a dollar more on amazon. It is also only available on amazon in 2x right now, just when I was ready to buy it. I would be swimming in it and I want to wear it out to promote the show. Totally bummed about it.

This is the one from the show: https://www.amazon.com/gp/product/B00XIHOIL4/ref=ox_sc_saved_title_2?smid=A3TKUBCADEEVXK&psc=1

And its almost twin: https://www.amazon.com/gp/product/B00II7DJZA/ref=ox_sc_saved_title_3?smid=ATVPDKIKX0DER&psc=1
