I recently received a knix gift certificate for my birthday. My first attempt with KNIX was my own money. I followed their sizing and the bra way way too tight and there were not enough band hooks. I returned for a refund on my credit card. I was happy with the refund process that time. My second attempt was using my birthday gift card. I bought the next size up and a different style. Still a lousy fit that allows my breasts to travel all over the place, even just working a desk. The cups (if you can even call them that) are way to small despite what their sizing suggests and they didn’t get bigger with 2 weeks of wear. They said they don’t have a bra product that fits me at the moment. I also bought a pair of underwear. The underwear fit is very big and far too tall. I can pull them all the way up to my bra with fabric to spare. I’m only 5ft tall. I paid part credit card/part gift certificate. They will only refund what went on my credit card. $12. The rest of my birthday gift is toast. They will only put it back on the git card, for which I can't check the balance. I’ve tried two styles and two sizes plus underwear. I don’t recommend this company’s products.
