    Love it, but it makes a lot of noise.

    It is great to have an underwire bra from knix, as I always felt I needed that lift the other bra's don't provide with a larger cup size. I do love this bra, but it is VERY noisy, it is always making "creaking" noises when I move. I have washed it SO many times. I have 2 and they are both like this. I probably won't buy another because of the noise it makes.

    4 Stars

    The underwear and the bra is fantastic but bigger cup size girls need more support. I am always confused as to why bra companies think that D cup and above girls should have the same support through the shoulder straps and the back as A cup girls. Bigger cup sizes need more support through wider shoulder straps and at least four latches on the backstrap to truly get the support the girls need.

    Wouldn’t purchase again

    This fit great when I bought it and seemed like it would have good support, but after one wash and wear the non-wire became weirdly shaped and now it is basically unusable. I waited to long to return, and will never wear it again. Definitely disappointed for the cost, stick with other styles!

    Good product.

    Good product Sizing is always a challenge with Knix. Every bra is different. Hard to get the size right when one boob is bigger 😜

    Just Awesome!

    I moved away from underwire bras almost 10 years ago, but still needed to reach for one occasionally because of the fit of certain tops/dresses. This freeflex demi is the first one that I didn't want to immediately rip off when I got home. And that says a lot! Time for more colours

    Love the Demi Bra

    It’s a great new bra. I love the lift and support that it provides. The underwire is quite comfortable and the molded cups are great to wear under a t-shirt. I liked the first bra so much that I ordered a total of 6 Demi bras.

    Very comfortable underwire bra!

    I had given up wearing underwire bras because they were so uncomfortable. Some clothing just looks better with these types of bras so I decided to try Knix's new underwire bra. It fits great and really supports me. I have ordered several more from Knix.
