    Great wire bra! But still want to take it off at the end of the day. The material is beautiful and the band it thick! I wish the middle section cups touched instead of having a small divide.

    Zero stars- do not recommend for anyone active

    I have loved almost every bra that has come from knix but this one fails. It does not have coverage for any active experience (being a busy mom this sucks). I just want to look nice in a smooth uplifting bra. I thought this was the ticket. I’ve tried multiple different situations, styles of outfits, level of mom days- if you need to bend over and do it the wrong way your boobs will begin to pop out of this bra.

    Adjusting your boobs in public isn’t acceptable for the most part so I’d look ridiculous until I could excuse myself.

    Basically you can’t be doing anything active- this bra is for going out and or sitting at a desk. Which I don’t mind but I bought it at high cost and regret the purchase substantially.

    Demi bra

    Not a good fit for me. Straps constantly falling off shoulders. Underwire digs in. Not comfortable at all. Too bad I am past the return date. Better bras out there for that money

    New natural bra

    Liked the more minimalist cup but slightly irritating in center piece area

    Dissapointed

    I love the print. I do not love the feel, very uncomfortable and as you move the bra makes a noise. I could not recommend it.

    Wouldn’t repurchase

    Even with an associate fitting me properly this bra when wearing for multiple hours a day gets quite uncomfortable. The underwire bunches together between cleavage and pushes into the ribcage.

    The fabric and look are amazing though.

    Awkward squeaking!

    I love the fit of this bra but its sooo noisy. It makes a squeaking sound thats so obvious when im walking through a quiet office.

    First wired bra in a while..

    This is my first wired bra in approximately 4 years. It's pretty good, fabric is soft and it is supportive. I'm not 100% sold on the fit but that could be because I'm not used to the structure. I do really like the flexi wire so hoping that I will find it more comfortable with more wears.
