- Rated 1 out of 5 stars1 month agoThey don’t fit their own bras
I bought these things hoping that the would fit my Knix bras better than the extenders I got on Amazon. Well they DONT. The connections are wider than the bra.

Nancy P.Verified BuyerWas this helpful? - Rated 5 out of 5 stars3 months agoBand Extender
The band expander is a perfect way to add a bit more width when the cup size is perfect but fit is tight.
Karen H.Verified BuyerWas this helpful? - Rated 5 out of 5 stars5 months agoWhat I needed
Exactly what I needed for my Revolution bra to fit perfectly.
Corinne D.Verified BuyerWas this helpful? - Rated 5 out of 5 stars6 months agoPerfect Extension
It’s exactly what I needed. Although your bras have plenty of hooks in the back, it’s always been a bit of a struggle to even connect it to the first hook. I’m not a big woman so, I wondered if it was just I didn’t have enough strength in my arms to stretch it any further than the first hook. However, the extensions alleviate that problem for me.

So happy this piece was an option!!
BrandieVerified BuyerWas this helpful? - Rated 5 out of 5 stars7 months agoLove it!
Recently tried a new Revolution style- the pullover bra. It fits beautifully and I especially like that the straps are somewhat wider than the regular style with clasp in back. Because of a painful shoulder, I step into the bra and it works as per another reviewer.
Thankx KNIX!

Game changer.
DeniseVerified BuyerWas this helpful? - Rated 5 out of 5 stars8 months agoThe fix you need
...if you purchased bras too small, these extenders are a fix.
Susan H.Verified BuyerWas this helpful? - Rated 5 out of 5 stars8 months agoLove my wingwoman bras!!
I find these bras very comfortable with great support. I love all the colour choices and the fact that they’re wireless is the cherry on top!!
