Guess that means I should start wearing velvet knee breeches like Oscar Wilde.

He does come up in a neat book I have, How the West Was Worn: Bustles and Buckskins on the Wild Frontier by Chris Enss; Guilford CT: Globe Pequot, 2006.

When playwright Oscar Wilde made the long journey from London to California, he brought with him a flamboyant wardrobe. In 1882 he attracted large crowds
of settlers in Leadville, Colorado, who were interested in seeing Wilde's velvet knicker suit and flowing bow tie. His outrageous costume was made complete
with a high-crowned, large-brimmed cowboy hat and knee-high cowboy boots. Although men found his fashion sense questionable, women admired the frilly,
soft-collared shirts he wore, and they made patterns of the garment so they could replicate the design for themselves. (70)
So there's my Irish heritage.
