    Didn’t work for me

    Unfortunately this did not work for me. I LOVE Knix underwear but have yet to find a bra that is comfortable for me. I found that this bra is very squeaky like other reviewers described. It is quite loud while wearing it. Also it is very stiff and very uncomfortable. It does offer great lift and is supportive for larger breasts. Sadly after wearing it to work, I couldn’t wait to get home and take it off.

    Comfortable, but can't stand the NOISE!

    I have never had a noisy bra before. This bra squeaks/creaks whenever you move. I think it may be the flex wire. My partner would hear it while I was driving it's so loud.

    On top of that the straps started curling and Customer Service said it was due to excess tension and that I likely had the wrong size. I was fitted in the knix store for a 42D. They don't seem to increase the strap length when you have a wider band size, which is silly. Also the bra doesn't hug the cleavage and sticks out; which is noticeable when wearing a t-shirt.

    I am SUPER disappointed. I have tried all of the knix bras and none of them worked. I thought I had found the perfect one. It was very comfortable, but I can't ignore the critical defects.

    Smaller fitting then other Knix bras

    I can usually wear a Knix 40 or 38 DDD/E and a Vic Secret 38 DDD- but I found these cups a bit small. I bought a 40 DDD fits almost like a double DD or even a 38 DD, I will have to return and there is no larger cup size to reorder.

    If it fit I think it would be more comfortable then a standard wire but not by much. It definitely gives you a bit of shape unlike most Knix bras. I mean I wear them for comfort definitely not shape or looks so I was hoping I might get both with this one. Maybe if they offer large cups - comfort with shape - keeping the dream alive. Haha.

    Verdict is still out…

    I am not sure if choosing a wire bra was correct for me. I did purchase 2 of these in store, after a fitting (the staff person was very helpful), but I feel the wire during the day which I was assured I would not. The other Knix non-wire bras I have I don’t ever feel like I have to adjust during the day, and these ones I do. They’ve been washed once. Maybe a couple more washes..? I dunno. I’m skeptical this was the correct choice for me.

    Nice bra.

    Not as comfortable for wearing all day long as my other Knix bras but it's great for a night out!
