It all began on ships. The Naval uniform was the inspiration for
the bellbottoms of the 60s. Then came something that looked... uncannily
similar.
Actually there were differences. Flares evolved from the radical
bellbottom style that had been promoted by hippies.
They had a more subtle shape and were flared from the knee down.
The circumference at the hem was much smaller than on bellbottoms
(more like the 'boot cut' of the millennium).
The flared-leg boogied on until the end of the decade alongside
skin-tight disco wear.
