I’m currently pregnant so have not nursed in it yet, but the bra is comfortable, supportive and has full coverage. I’m usually a 36 F or G and I would say the size chart is true to size (I ordered XL). The only thing is and this is with most sports bras your boobs don’t look great in them, but the comfort and support is there and that’s what I needed right now being 7.5 months pregnant. Comfort being a must! It’s a good sports bra, I would recommend it to bigger chested women who struggle finding decent sports bras!
