Bras were no longer seen as just a utility, but more so as fashion statement. Designers started incorporating numerous devices to produce varying shapes, cleavage, and to give women bras they could wear with open-back dresses, off-the-shoulder dresses, and plunging necklines, etc.
Though fashions will go in and out, it seems as though the bra is here to stay for quite some time. We have come a long way from the steel and whale-bone corsets from what now seems like the ancient times; and with fashion changing, plastic surgery growing, and other technology advancing, we will always have a long way to go.
