I think we can all agree that the that the ultra feminine looks on Mad Men are infinitely appealing. The 1950s was the only era to fully embrace the hourglass figure. The pointed shoulder pads and straight tailoring of the 1940s faded out after the war and the ultra feminine shape emerged with clothing emphasizing womanly curves. Definitely the most flattering era for women. You can note from the sizing of the vintage dresses that women had very tiny waists (at 23 to 26 inches!) during that time but the bust was roomy for those nice pointy bras.
