Have these in 6 colors, they're great layered or alone. It's not racerback, so no special bra - yay! My bra strap is hidden perfectly and the top rarely shifts enough to reveal it. It's very forgiving in the waist if you tuck the front. I 'm a size small but these run large, so I get XS. Accidentally ordered a small once and it was very loose around the armpits and hanging like a bag. I'd say size down for sure.
