Women's Plus Size Costumes

Our costumes are designed to hug in all the right places. Many styles include stretch, but will fit more snugly than everyday clothing. Between sizes? Go up for a more comfortable fit. Check the size chart on each product page to be sure.

Each style includes the main pieces that create the look—such as a dress or bodysuit. Some styles include select accessories. Check the product description for exact details.

To keep your costume looking its best, we recommend hand washing in cold water and laying flat to dry. Avoid bleach and high heat, as delicate fabrics and trims may be damaged. Always follow the care instructions listed on the garment tag when available.

Halloween costumes can be returned if purchased outside of the designated Halloween final sale period. Orders placed during the Halloween cutoff window are considered final sale and are not eligible for return. Some Halloween costumes may also be marked final sale regardless of purchase date and are not eligible for return. The 2026 Halloween cutoff dates and times are yet to be announced.
