They are not so bad when not taken to extremes like others have said. Plus they make my bust extra busty. You want a custom one though. It's far more flattering when your bust isn't spilling out of your top, but sitting there nicely on display. Proper fit is important after all. : 3
Custom always seemed like it would be expensive. Of course, I've never looked into it.
And I always liked the pressure. It's pleasantly compressing! Then again, I've never done anything crazy (no 16 inch waists here). Yet.
