I've tried Playtex 18hr bras before and have never had much success with them.  They either don't fit right, pinch in the wrong places, or are made with nasty rubber that sticks to my skin.  This bra is pretty, it comes in 5 different colors, and it is extremely comfortable.  I have worn this bra beyond 18 hours, and do not feel like I'm getting out of a corset when I take it off.  I also like the fact that this bra lifts me (where others do not) and make me feel at least ten years younger.  They are also a great price.
