What our customers are saying
Customers say this bra extender provides comfortable extra room when bras feel too tight. Many reviews mention its usefulness for new bras that need breaking in, weight fluctuations, or bloating days. Users appreciate the soft, comfortable material that's barely noticeable when worn. Common feedback includes praise for the quality construction and effectiveness at solving fit issues. Several customers note it works well with various bra styles, particularly sports bras. However, some mention sizing concerns - the three-hook design doesn't match all bras, with requests for two-hook options. A few wish for more color choices beyond the current selection. Overall, reviewers find it a helpful accessory for achieving better bra fit.

    comfort assist

    I love this extender. I find that I get a better fit by using the extender for the first few months and as the bra relaxes I stop using it. When I go with a larger band size it becomes too loose and that is not so easily adapted. This is a helpful extra

    3-hook band extender

    If I could 10 stars I would. I know I had some issues with the fit and you graciously provided me with ideas, suggestions, and a 3 hook extender which solved all my problems. I was able to go down in size which fits much better and I no longer need the extension due to everything being more of a relaxed fit. I appreciate the back and forth texts to get the problem solved, and I couldn’t be happier. I in fact ordered another 5 more bras because they are amazing and I love the fit, feel, and comfort. Thanks again for taking such good care of me🥰

    It does what it should

    Bought for my WingWoman bra. I have gained weight since I bought it and the band did not extend when my body extended. A couple of notches more, fixed the problem.

    Perfect fit

    This was exactly what I needed to give just a little more room in my current bra. Thank you for having both 2 hook and 3hook available.

    Adds that little bit extra so I don't have to purchase new bras.

    The band extender is an inexpensive way to make your current bras fit due to a temporary weight gain.

    Sometimes this is all you need

    This is all you need for many reasons you might be a size in between or you get pregnant and your bra size changes.. It is practical they match the material of the bras and are well made. And very affordable. I have used both the 3 hook and 2 hook band extender and both are soft and comfortable.
