I've been struggling finding the right everyday bra lately. I use this for everyday wear, including sleep. I am a size 40D and the 2X fits perfectly. I don't constantly adjust it. The band rolls a tiny bit, but that's because of my body shape, it's not the bra's fault. I like how it doesn't show under t-shirts or thin sweatshirts, sometimes I wear just this bra under my hoodies. I have a chronic health condition that makes me sensitive to seams and garments that are too restrictive. This bra makes me so happy. I have two and I need more because I'm never wearing another kind bra if I can help it.
