I bought this bra to see if it would be a good underwire version of my favorite wireless T-shirt bra. I'm a comfortable 40D, no spillage on top, sides or back. The cups give great support - lift the girls up almost an inch - and between the cups and the sheer overlay, I have full coverage. Fabric, band and cups are very soft. It's invisible under a T-shirt. The cups hold the girls in on the side and make them look natural, unlike another underwire of mine that makes them smoosh sideways. The sides come up to the bottom of my armpit, so it might show if you wear a tank top. I give it 4 stars because the underwire isn't integrated into the cup, so it takes some adjusting to get it to set right. I'll wear this with work clothes, where my stretchy wireless bra might not give me the right profile, and with casual shirts as well.
