Get an Exclusive Look Inside Heidi Klum's Halloween Party, Courtesy of the Elevator Boys

"Touched down in New York and on the way to Heidi Halloween! We came back to New York this Halloween to attend our favorite Halloween party. Last year, we dressed as a bloody boy band, so this year we wanted to shake things up . . ."

"This year, we decided to team up with HateAid, a nonprofit that supports those affected by cyberbullying. We worked with Louis Willenberg, a Berlin-based designer, to create our costumes, which shared the messages: 'Scarier than any costume,' 'Stop hate — now,' 'Human rights also count online,' 'Over 50% of young people experience hate online,' and 'Hate can kill.' We're particularly passionate about this message because it primarily affects our generation."

"Happy Heidi-ween! We arrived at the venue, Marquee, and were super excited to show everyone our costumes. We couldn't wait to see what Heidi would be this year!"

"Here we are, sharing our message at Heidi Halloween. Being in the public eye, online hate has become no stranger to us and many others. It causes a lot of suffering, so we decided to use our reach to educate others and as a call for solidarity for others experiencing online hate."

"At this point, we took a break from the party to check out our photos with our friend and videographer, Jojo Kapol. He's always on top of his game and getting us the best photos to share online. We were excited to see what everyone thought about our costumes!"
