Jokes apart, if one tries to seriously muse on Galliano's thought process behind the look, one can see his favorite historical reference namely the Merveilleuses(for more on this refer to Understanding John Galliano) being alluded to.How so? Look at the picture below to see where he would have sourced his inspiration from!
"Ah! s'il y voyoit!" ( "Oh, What if he could see!"). Library of Congress description: "Print shows two fashionably dressed women walking on a country road and a "blind" beggar with a small dog on a leash and holding a cup and stick in right hand. The man has stepped on the skirt of one of the women causing it to tear, exposing her bare buttocks for the "blind" man to see. A satire on contemporary clothing fashions."
"Contemporary clothing fashions" refers to the fashion of 1790's(the caricature refers to 1797 to be very precise) when the Merveilleuses dressed themselves in several yards of almost transparent sheer fabric.
