I have been looking for years for a comfortable, t-back, underwire, affordable bra.  Bought two of these, one in beige, one in black.  So comfortable I don't have a problem wearing them all day, and love that the straps never, ever slip down.  The front closure is nice too. I wear a 38C and like the way they look under sweaters, vests.  A little problem on a cold day in a tshirt, but I found a great little product called Bra Discs to insert and wear on those days for added coverage.  Will buy more of these bras!
