These are okay. I'm 7 months pregnant and my ribcage has expanded at least a full band size (from 34 to 36+). These are nice in that they stretch, but that can also be problematic keeping your 'girls' UP INSIDE the cups. Also, the hooks don't seem to stay hooked well once you've undone the bra -- meaning you need to rehook ALL 4 hooks from extender to bra...then the other 4 hooks to the other side...every time you put the bra on and take it off. Otherwise, it just dangles by 1 or 2. Not the end of the world - just cumbersome.
