Baby vampire costumes are typically made from polyester or polyester blends. Some styles use plush fabrics such as minky or velour for accents and details.
Baby vampire costumes usually span infant and toddler sizes. Commonly offered ranges are shown as 0–2 years for infants and 2–5 years for toddlers.
Wigs and hoods rely on snug construction—such as elastic-edged mesh caps—or chin straps with hook-and-loop fasteners to help keep them in place.
Wigs are typically synthetic hair mounted on a mesh cap with an elastic edge for fit, while some hats feature a boucle outer shell with a jersey-knit lining for comfort.
Infant bodysuits often include snap-button closures for easy diaper access, and many bottoms use elastic waistbands or stretchy ribbed waists to maximize comfort.
