Hannah Rose Dalton recently posted an image to Instagram of herself in a pink outfit. But this wasn’t some Barbie princess fantasy. Instead she wore a draped wrap jacket over a feathered skirt, 15-inch-tall platform boots without heels that gave her the appearance of levitating, and a neck brace.

A design resembling barbed wire or lightning bolts ran from her cheek along the side of her bald, conical head; there was a smooth patch where her nose should be, and her eyes were a blank sea of putrid yellow. The caption read, “Gurl bye.”

In another post, Ms. Dalton stands alongside Steven Raj Bhaskaran, her partner in life and business, who prefers the gender-neutral pronoun Mx. and wears a white buttoned shirt and leather harness over a black asymmetric skirt and towering black platform boots.

From Mx. Bhaskaran’s mouth hangs a long black appendage, like a swollen tongue or overgrown tail. From the sides of Mx. Bhaskaran’s head dangle two stringy black locks of hair. In the background, a man on his cellphone looks on in confusion.
