I have both Grover's and ACD. Cottonique has some 100% cotton elastic free options, yet if you are large breasted you won't get much support. The side tie doesn't work at all. Their 100% cotton 3 front tie bra is adequate. Yet you will have a lumpy look under a knit, but fine with a 100% cotton or polyester button down shirt. The most comfortable one for me with small breast is their bra liner. It has a casing at the bottom with latex free elastic. I am not allergic to latex, but a different element in rubber, MBT which is in most elastic, spandex and blended fiber. I open the casing and remove elastic and replace with 100% cotton drawstring.
