SI Swimsuit models are big fans of Halloween. It’s a day to get creative, dress up, rock funky new styles and go full-glam—how could they not love the holiday?

Each Oct. 31, our Instagram feeds are blessed with the most unique costumes. From Paige Spiranac’s promised 31 days of costumes to Heidi Klum’s annual Halloween bash, we keep track of everything our models get up to during spooky season.

You’re in for a treat (pun totally intended). We scoured the internet to pick out some iconic looks that you’ll appreciate being reminded of, as well as some super stunning old ones from the archives that you might have forgotten about.

Below are some of our favorite SI Swimsuit model costumes over the years.

Katie Austin and Christen Harper As Charlie’s Angels
