Very good support in a non-underwire bra. Seems well-made, with quality fabrics. The cups do have seams (diagonal), but they lay flat and are not irritating.
This bra is described as cotton blend. Be aware that the fabric blend contains more polyester and nylon; much less cotton. Not as much cotton as I had hoped, but the fabric is adequately comfortable. More comfortable than typical support bras.
This 'active' bra is somewhere in between a serious sports bra and a normal, everyday bra. This is not a flimsy leisure-type bra.
About the same time, I ALSO bought a different style, the 'Glamorise Sport Wirefree Bra', style number 18943 . The two styles have similar shapes, but the sizing is different. I am between two sizes. In that Glamorise Sport Wirefree Bra, the fit was extra snug, and I needed the larger band size. This here bra, the Magic Lift Plus Active Support Bra, has a looser fit; the smaller band size fit well. Also, the cup sizes for this bra may be just a little larger than typical.
