Stretchy

No support hurts back if you are large chested. Very pretty color and design just not good for working out.

Hi Katina, we are very sorry to hear that our 1RM did not provide the support you were looking for. If you are looking for our most supportive sports bras for larger chest sizes based on reviews those would be- X-Factor, Moxie, Crossfire, and Intensity. Also please know that if you ever have any questions about a particular style before purchasing our customer service team is always standing by to assist, so please do not hesitate. :) - contact@bornprimitive.com

My #1 favorite bar

The freedom of movement in the back is the best! Doesn't pull on my traps. Doesn't tickle or leave weird lines. No shifting or adjusting. I originally bought a small (32C) If fit but felt TOO tight and was very hard to get off. Exchanged for a Medium and it was just right. Not loose- no stretching out. Still supportive.
