Infant avocado costumes are offered in multiple baby sizes. Listings commonly show 0–6 months, 6–12 months, and 12–24 months, and some items use a Small label that corresponds to a 6–12 month range.
Many avocado costumes are made from 100% polyester. Some infant versions use plush Minky fabric or fleece and include a fiber-filled seed construction for a softer, stuffed look.
Fastening varies by design: some infant jumpsuits use snaps for diaper changes, others have a front zipper for easy changing, and many tunic styles use a hook-and-loop fastener at the neckline.
Adult avocado costumes are described using general adult sizing; some listings specify "One size fits most adults."
Descriptions highlight plush construction such as pillow-soft collars, foam-lined bodies, and fabrics noted as comfortable enough to wear all night.
Care varies by item: some adult tunics specify hand wash only, while some baby options are described as machine washable with a recommendation to hang dry.
Designs commonly include a soft brown or exposed avocado pit detail and a stem-and-leaf hood to complete the look.
