I was looking for a comfortable, wire-free bra that would stay on my shoulders without being a sports-bra/uni-boob style. Knixwear does offer an unconditional 30-day return on the bras, so I figured I had nothing to lose. I have a terrible time with my right bra strap sliding off because decades of hauling a heavy briefcase on a shoulder strap on that shoulder have left it really somewhat deformed. For decades, I've had to wear racerback or rig extra velcro straps across the back to wear a bra. This is complicated by the fact that I'm full-figured - 42D. The Knixwear 8-in-1 worked. Comfortable and the straps stayed in place. Nice support and shape.
So, I wanted to try the underwear but was not happy about the no return policy with the cost involved. So, I started an email correspondence with Knixwear. They offered advice and information and, surprisingly, offered to accept a return of the underwear if necessary because it was my first underwear purchase. I figured trying the underwear was then risk-free because I had the promise in writing in an email.
I was lucky. The Athletic Boyshorts they suggested worked. No roll down on my less than flat stomach (which I normally get with hipster fit) and comfortable fit across my rear with no uncomfortable ride up. I admit that they are a little higher cut on the rear than I like, but, maybe because of the very soft, seamless fabric, I don't notice any discomfort from riding up in my crotch. I put the underwear through a full day of sitting, walking, squatting, etc., before ordering more. I even washed it out in the sink to see how quickly it would dry (2 hours in our dry climate) and whether it would affect the fit (it didn't).
So, now I have all new underwear and bras. The coupons for first-time purchase help with the price. The kits give a good discount if you are buying bras and underwear. Still, it's not cheap. However, to me, it is worth it because of the quality and comfort. If not for the very responsive, helpful customer service, I wouldn't have tried the underwear.
Bottom Line: Yes, I would recommend this to a friend
