A khaki vest, a toy brush, a magnifying glass, and cardboard fossil bones in a belt pouch. Twenty-five minutes, easy: a khaki or tan vest with pockets, a toy paintbrush, and a toy magnifying glass. The bones should peek out of the pouch. Hidden props don't get compliments.

Still need:
Tip: crumple the brown paper bag into a specimen bag and label it.
Sizing: Built for kids and adults. Start from clothes the wearer already owns in their size, and size the vest and pouch against them before the fitting. The paper bag is a specimen bag, not a mask, so it needs no face opening.
Steps
- Draw bone shapes on the cardboard: a femur, a rib, a skull.
- Keep them chunky.
- Thin cardboard bones snap.
- Cut the bones out.
- Shade the edges with the pencil.
- Tuck the bones into the pouch so the tops peek out.
- Safety: Round all cardboard corners, and carry the brush bristles-down so nobody gets poked. Under 3: skip the bones and magnifying glass as carry props. Toddlers mouth everything and cardboard snaps. The vest and pouch alone carry the costume.
- Wear the khaki vest over a plain shirt.
- Put the pouch on the belt and the brush in one pocket.
- Ages 3+: add the magnifying glass to the other pocket.
- Optional pro finish: crumple the brown paper bag into a specimen bag and label it.

Common questions
How do you make cardboard bones look like fossils?
Cut them chunky, shade the edges with pencil, and rub a little dirt-colored eyeshadow into the surface. Uneven shading beats perfect coloring.
What goes in the belt pouch?
The cardboard bones with their tops peeking out, plus the brush. A pouch that bulges with finds reads as a real dig kit.
