What should a performer wear under a mascot costume?

The costume's padding creates the character's shape, so the performer's own clothing should disappear: thin, close-fitting, and breathable. Mascot work is athletic - performers run, dance, and gesture in an enclosed suit - which makes sweat management and foot support the two real priorities.

A practical under-layer checklist

• Top: a lightweight athletic shirt (synthetic or synthetic blend, not heavy cotton).
• Bottom: athletic shorts or leggings that stay put while moving.
• Feet: supportive athletic shoes with good soles; the character feet go over them.
• Head: keep hair secured and away from the face; performers rely on the head's interior harness, not their own comfort adjustments.
• Optional: a cooling towel or hydration plan for hot-venue events.

What to avoid

• Hoodies and sweatshirts: they compress the padding's fit and trap heat.
• Denim or stiff fabrics: they restrict the movement the character needs.
• Anything with hard edges (belts, buckles): they press into the performer under the suit.
• Perfume or strong scents: the costume interior holds them.

Hygiene note: because the under-layer absorbs most of the sweat, it should be laundered after every appearance - it protects the costume's interior from body oils and odor, which extends the intervals between the costume's own cleanings.
