"Torpedo tits" were mostly the result of the bras women used to wear and sometimes enhanced with the help of foam rubber falsies. In those days many women also wore girdles to slim their hips, tummies and butts. Merry Widows and corsets were also quite popular in those days for that hourglass figure.
I'm surprised with all the different fettish stuff out there, you don't see that as a niche. But it could just be my weird hang up

And man, the Score group has never let me down.
