I've been wearing this style bra for several years now, and love it.  The shoulder straps are just wide enough to give that little extra bit of support, but not so wide as to be noticeable under clothing.  The cups are smooth and the underwire is barely noticeable.  The one that this purchase replaced was at least five years old, washed at least once a week with her sisters, and only gave up the ghost when one of the wires broke and poked through the covering and, painfully, me.  When I was heavier it would have been nice to have the next larger size (42), but no complaints now.  I hope they make this bra long into the future.
