Love the straps. They stay up. The cups are comfortable, but in comparison to the other Wacoal bras I have, this style has cups that run large. The sides do not come up very high so there's a spill over under the arm.  All in all though, I have had a hard time finding a contour cup that the straps don't fall down on so I am going to order another one in a smaller cup size and see if it fits better.
