the new full cup bra. the fabric is 90% organic cotton and 10% spandex from recycled PET. The cup is a little higher cut and stretches to fit larger cup sizes. The straps are 3/4 inch natural elastic. The model in natural wears a M and is a 32DD. Model in mauve wears a S.
Sizing based more on band size than cup size because the spandex is more flexible. Here is a loose size chart that we are still refining as we try the bra on more women.
30 A-C is a small
32 A-DD is a medium
34 A-DD is a large
36/38 B-DDD is an x-large
