For the most part, I've always gone back to Playtex and once again, was not disappointed.  This bra has no underwire which I've been hesitant to buy but it works for me! I now have 3 colors, black, toffee, and beige in this style because I was so happy with the first one I ordered.  Straps do not slip down the shoulders, and are comfortable; there's plenty of support and still manages to remain comfy.  I do a long walk every day and sometimes I forget I even have it on which is unlike all my other bras which I dreaded every time I had to put them on to go walking! Now I walk in total comfort.  In my opinion, this is the best bra ever!
