Guests also ask:

Most are polyester-based: many listings show 100% polyester or 100% polyester poplin/jersey, while at least one option is listed as a 90% polyester / 10% cotton blend.

These costumes are sized for kids and commonly list suggested ages ranging from about 4–6 years up to 5–12 years; some listings also show a specific 8–10 years size.

Closures include buttons on jackets (sometimes at the shoulders) and hook-and-loop fasteners (Velcro) used on belts or at the back/neck of jackets to make dressing easier.

Jackets often feature printed elements like faux buttons and pockets, ragged hems, and colorful 'stain' or experiment-themed prints to create a worn, lab-used appearance.

Listings commonly show either 3-piece or 5-piece configurations, depending on the specific costume.

Glove styles vary: some costumes include black gloves with printed green 'stains,' while others include jersey-style gloves with wide, flared, stiffened cuffs.

They are labeled as kids' sizes and usually list a suggested age range. Some listings also advise checking the size chart to confirm the best fit.

Belts are described as faux leather or wet-look vinyl. Goggles are often described as faux leather with clear plastic lenses, and some listings provide plastic eyeglass frames (typically without lenses).
