BUILD_BRIEFING // HOW TO COSPLAY SANS

SKELETON IN A HOODIE

DOSSIER_v1
CRAFT_ANALYSIS

▸ VISUAL_DESIGN

A blue zip hoodie over a white tee, black basketball shorts with a white stripe, and pink slippers — worn with a skeleton skull mask or full skull makeup with two dot eyes. Casual and lazy on purpose; the head is the entire craft.

▸ DIFFICULTY_LEVEL

APPROACHABLE

◆◆◇◇

The clothing is a thrift run. All the difficulty is in the head: a mask that keeps the wide grin and hollow eyes while letting you see and drink is a genuine design problem.

▸ KEY_COSTUME_ELEMENTS

01Blue zip-up hoodie (fur-lined hood)
02White t-shirt + black athletic shorts with white side stripe
03Pink fuzzy slippers
04Skull head — mask, helmet, or full white face makeup with hollow eyes
05Blue LED left-eye effect for photos
06Skeleton gloves / white hand makeup

▸ SOURCING_NOTES

→Head: 3D-print or foam-build with mesh-covered eye sockets so you can see out and cameras still read them as hollow.
→Blue eye: a single blue LED behind the left socket with a diffuser gives the Gaster-blaster look.
→Clothes: thrift entirely — buying a 'Sans costume' set gets you thin printed polyester.
→Slippers: real pink slippers, not costume shoe-covers. People notice.
