FREE BRA® is made of 100% viscose which is a natural fiber that is softer than cotton yet more springy than silk. It is extremely comfortable to wear for floaty summer skirts and figure-hugging dresses, even those with plunging necklines. The comfort comes from the fabric's unique ability to absorb sweat so you can also feel confident. FREE BRA® has numerous features that you will appreciate and love. Take a look at our product line and you'll see that we offer a variety of solutions to comfort, support and confidence, which we promise to deliver.
