The fake animal head was attached to Jenner's strapless, body-hugging gown made from velvet, which she paired with gold-toe heels.
As Jenner said on Instagram, the piece was a "faux art creation constructed by hand using manmade materials" like foam, resin, and wool.
Though celebrities like Shay Mitchell praised the look in the comments section of her post, other social-media users took issue with the realistic-looking animal head.
"Even though it's not real, it's still disturbing and in bad taste," one person wrote.
Schiaparelli said on Instagram that the fake animal heads featured in its show were meant to represent the "lust, pride, and avarice" present in Dante's "Inferno" — which served as inspiration for the runway show.
