As a non-binary person with a large chest, finding binders/bras that are both comfy and work, particularly as a wheelchair user is not easy. I technically am out of the size range (53I), but due to the degree of squish my boobs put up with, and thus facilitating bands sliding up over them, a tighter band was desired. The 5X did fit as I expected, and is very sensory friendly fabric which at the same time put up with 2.5km of walking my dog in my wheelchair without my boobs escaping or too all over the place with the movement.
However, if you are sensory sensitive, the bra was treated with scented products, and my lungs did not appreciate that at all. It will hopefully come out in the wash, but it was not the most fun surprise, as it intensified on wearing.
