Christian Siriano’s live fall runway show once again prove the feel-good power of fantastical fashion.

The collection consisted of second-option celebrity looks and leftover fabrics from some familiar gowns.

It was fashion with a capital F. Make that three Fs: Fashion, Fantasy, Fun.

Inspired by “Birds of Prey” superheroine Harley Quinn, the designer’s audacious fall collection featured a range of badass evening looks.

Inspired by interior design, Siriano experimented with tailoring in playful ways that allowed the clothes to balance modernity with a sense of youthful cool.

The red-carpet go-to’s spring show amped up its typical more-is-more aesthetic.
