fat suit costume

Most options use polyester-based fabrics—many list 100% polyester or lightweight polyester for inflatable suits. Plush or 'plumped' costumes commonly use faux fur or minky fabric with fiberfill/polyfill stuffing to build and hold shape.

Inflatable suits use a built-in fan or pump for inflation and commonly require four AA batteries. Listings often state the batteries are required but not included.

Most plush suits fasten with a back zipper, often paired with hook-and-loop (Velcro) closures. Infant styles may add snaps along inseams for diaper access and chin straps to secure headpieces.

The plump silhouette comes from stuffing and built structure: fiberfill or polyfill in belly and body panels plus foam backing or structured panels in the torso and upper areas to produce a rounded shape.

Listings commonly indicate general adult or men's sizing, and many items are labeled 'one size fits most.' A smaller number of listings include specific measurements (for example, some show chest up to 41" and waist up to 36.5").

Comfort features include lightweight construction and linings for easier wear, soft minky fabric or satin linings in plush suits, and built-in fans in inflatable costumes to maintain shape and airflow during extended wear.
