“Took a chance on becoming a member before I'd even tried out any TK Basewear, and I'm already loving it. I received my first set quickly after joining and immediately tested the bra out on a run — I have never worn such a comfortable sports bra! Can't wait for the next batch to arrive!”

“The membership is a great deal. You get your money's worth with the initial shipment and early access is imperative because they sell out so fast!”

FAQ:

What is the difference between the Low Cut and the High Cut?

The Low Cut is as minimally designed as possible, with as little fabric as necessary. It is best suited for athletic builds and cup sizes A–C. In contrast, the High Cut can accommodate up to cup size DD with the same flattering design.

Where's the fun colors?

We are committed to sustainability, and part of that journey meant switching to fabric that is made from recycled plastic bottles. With this new fabric, we are more limited in our ability to produce colors. Someday we will create new colors for the TOURA, but it won't be anytime soon. For now - embrace the stealth look! Mother nature will thank you. ❤️

Can I wear a Low Cut if my cup size is above C?

Yes... but at your own risk! Those above C who wear the Low Cut say it's best for lounging at the beach, or when they want a more busty look. That said, you are at a high risk of popping a nip out of the top. The Low Cut is best if you have more pec muscle than breast tissue. Otherwise, High Cut is the way to go.
