I have worn this particular playtex bra for years. It has the best support & comfort of any , you have the best selection of color & sizes, this is the main reason I ordered from Amazon . Thank you

Playtex siempre de muy buena calidad y ajuste, en mi caso , la copa estaba un poco más grande, tuve que pedir una talla en copa más chica. Llegó en tiempo.

I always buy this made bra because it fits good. My favorite.

I love this bra. This is the only one i use regularly. I wish playtex was available in India.

Great fit. Very good supporting bra!
