This year Halloween happened to fall on a Thursday, coinciding perfectly with NightLife at the Academy of Sciences. The museum was bustling with fabulous costumes, creepy science exhibits from The Bay Area Science Festival, and a drag show featuring Peaches Christ. Check out her spooktactular look, plus our favorite costumes below. 

Infamous SF drag queen, Peaches Christ, unrecognizable as a "silent film vampire". The custom costume was designed by Amie Rodgers.  

Kathy Winship in a DIY Bijork swan costume. Her look included a poncho-turned-skirt from Thrift Town, fishnets from Multikulti, and duck washcloth to complete the look.

Al Claxton as the "Prince of Darkness." Pieces of his costume are from New York Apparel on Haight, Fantasy Clothing in SoMa, and various online shops.

Jackie Yanez, dressed as a Native American. She found her fabulous feather headpiece on Etsy, got the dress from Party City, and moccasins from Aldo. 

Robin Russell, dressed up as an "intergalactic black widow." Her traditional samba outfit was purchased on eBay.

Events coordinator at the California Academy of Sciences, David Nemoyten, dressed as a scary clown. His costume was custom made by a friend, with makeup by a NightLife face-paint artist. 

Linden Cady as She-Ra Princess of Power. Her costume was self-made with pieces from Piedmont Boutique and Salvation Army. Her gold platform Sketchers boots are a vintage pair she kept from high school.

Edwin Kim, inspired by Colin Farrell in "S.W.A.T." This was definitely one of the best costumes-in-a-bag we saw, made super chic with Louis Vuitton aviators, a Chaumet watch, and BOSS sneakers.
