I bought this bra because I saw a recommendation from a busty influencer, but I wouldn't buy it again.The material isn't breathable at all; I sweat excessively underneath it, even though I've never had problems with excessive sweating before. It's so bad that after a few hours it leaves a wet patch on my top—very aesthetically pleasing!
Furthermore, the size is quite large, so it's rather loose, offering virtually no support. Wearing it at home is probably fine, but even brisk walking would be uncomfortable.
I am 34G, and I chose an XL+ as a reference.
