The Billie Eilish & Finneas Collection, in partnership with John Hardy, is available online with prices ranging from $195 to $2,400.

The organization's marquee fundraiser will take place at L.A.'s Skirball Cultural Center on Nov. 19.

The campaign makes use of their talents beyond being just pretty faces: "We take suiting seriously" pairs still photography shot by Luke Gilford with a comedy short penned by the trio and Brady Lees.

The pair will share the spotlight at the Women's Guild Cedars-Sinai's Stardust Ball at which Byron Allen will be celebrated with a trophy for his humanitarian work at the Beverly Wilshire on Nov. 18.
