I love this bra!  It's may favorite of all time.  I use it daily with my dressy clothes too.  It does a great job with support without mashing down my breasts.  I haven't tried running in it, but I do a lot of walking and it is great!  The cups aren't padded, but there is enough material thickness to have some degree of modesty.  The material is not thick enough to prevent the nipple action from showing though.  As I have lost weight, I notice as the sizes get smaller, so did the number of hooks in the back, which is fine with me.  All in all I am quite please with it!
