I just bought a few Bendon Pregnancy bras last week, they have 'flexi wire', which basically goes from around the side (not right up next to the boob like normal underwire) and underneath, but doesnt come up the center, so the middle of the bra is almost like a crop top. Its taking some getting used to (ok the lace on this one I'm wearing today is driving me INSANE.
oh yeah, and I have gone from 14D to 16E so far!
