The Bullet Bra

In 1949, they spark a global trend with a new design called the Chansanette. In 1950s actresses with apparently massive chests, it's because the bullet bra simulated a larger breasts and with like a point on the front. They're very conical. There's a lot of actresses from that in like sweaters and then basically triangular shapes are under the sweater. That was the bra style and the new trend was like, oh, your breasts are supposed to be that shape now.
