I'm surprised with how many negative reviews there are of fabletics. There are no surprises/secret. It's right on the website as to how the site works. The fact that people thought they can get 1/2 off the first outfit and that would be it, it surprising. The site also explains that you can cancel you membership any time or decline the purchase for the month by the 5th. It's pretty self explanatory.
As for the clothes, I do a lot of cross fit and spin classes. I find the clothes durable and comfortable. Love the patterns they offer.
