Sports Bra FAQs

Sizing can be a bit tricky and Knix sizing might be a bit different than what you’re used to, but we've got you covered! You can check out all of our size charts here or book a Virtual Fitting here

The way that we size our bras at Knix is to allow different body types to fit into one size. The flexible 5 row hook & eye back closure accommodates your personal preference and level of comfort for the underband.

No, all Knix bras are wireless! Wireless bras give you freedom to move and feel your most comfortable and confident self.

Yes, you do. 

Your underband measurement will equal an alpha size. 

For example: 

XXS =28Band, XS=30Band, S=32Band, M=34Band, L=36Band, XL=38Band, XXL=40Band, XXXL= 42Band 

Regular size cups cover =  A - DD 

Plus sizes cups cover =  E - G

We recommend scheduling a Virtual Fitting with a Knix Expert or consulting with a team member in-store.

We find that gaping in the armpit area can mean that the band of the bra is fitting too large. So, we recommend tightening the band of the bra and adjusting the straps so you have a snug but comfortable fit.

Wearing the bra for the first week is also helpful to allow the bra to relax and mould to your natural shape! 

Try making sure:

a) The strap is well adjusted and tightened to minimize the side wing gaping. 

b) Adjusting and tightening the underband.
