This is the first bra I have bought that actually fits without needing an extender band. I have spent years going to full figure stores and nothing came close to this. The back (band) size is 44 and actually fits so I can easily reach it to pull it together in the back without breaking my arm. No fat rolls in the back. Looks great under t-shirts. This is really designed for full figures.  Vanity Fair got it right. Finally, a company that uses realistic models. Love it!
