Costume details & sizing
Premium Plush Fabric & Construction
Every Squishmallow costume in our collection uses the same ultra-soft polyester-spandex blends that make our plush toys so irresistibly huggable. We work with specialized costume manufacturers who understand the unique texture requirements that define the Squishmallow experience—that marshmallow-soft squish that fans recognize instantly.
Our costumes feature double-layered construction in high-wear areas like knees, elbows, and seat panels to ensure durability through multiple wears and washes. The exterior plush maintains its softness even after machine washing, while the breathable cotton-poly lining prevents overheating during active play. Each costume goes through over 100 quality checkpoints during production to meet our brand standards.
Sizing & Fit Guide
Our Squishmallow costumes are designed with the same generous, huggable proportions as our plush toys. Youth sizes (S, M, L) fit children ages 4-12 based on height and weight, while adult sizes (S through XXL) accommodate a wide range of body types with adjustable elastic features at wrists, ankles, and waistbands.
For the most accurate fit, measure from shoulder to ankle and compare to our size chart available on each product page. We recommend sizing up if you plan to layer clothing underneath for warmth, or if your measurements fall between two sizes. The relaxed fit ensures comfortable movement for trick-or-treating, dancing, or convention floor walking without restriction.
What's Included With Each Costume
Every Squishmallow costume purchase includes the full character body suit and oversized character head or hood attachment, depending on the specific design. Cam, Fifi, and Benny costumes feature separate headpieces that slip on over your head, while Avery includes an integrated hood design for easier wearing.
Costumes with character-specific accessories like Benny’s oversized feet covers or hand mitts include those pieces as part of the complete set. All costumes come with our official Kellytoy authenticity tag and care label with washing instructions. Base clothing (shirts, pants, leggings) and shoes are not included—we recommend solid-color basics underneath that complement your character’s color scheme.
