"This is [by] one of our 'Project Runway' designers," Klum told Us Weekly on the red carpet. "This episode will air this Thursday. We gave the designers a challenge to make a Creative Arts Emmys dress for me. They had 12 hours and a budget of $200. And this is what happened."
Though the design is stunning, Klum admitted it wasn't necessarily a practical choice on her part.
"It's not that comfortable," she admitted. "It's very heavy. It's just held up by these little straps."
Klum paired the detailed look with a gigantic Lorraine Schwartz sapphire necklace.
Sean Kelly is one of 12 designers remaining on Season 13 of the Lifetime reality series, but if his design was worn by Klum at such a prestigious event, he likely has an edge on the rest of the competition.
