Collection: Plus Size Costumes

Plus size costumes are fancy dress cut in a wider size range so the fit is comfortable through the shoulders, chest and hips rather than just stretched from a standard block. Check the actual size chart on each listing rather than the label alone, since plus size ranges vary between brands, and go up a size if you are between measurements. Start with a costume style you already feel good in day to day, then look at our women's costumes and men's costumes for the full range in your usual size.

Getting the fit right

Every brand cuts plus size differently, so check the garment measurements on the listing against your own rather than relying on a single size label. Costumes with adjustable ties, stretch panels or a looser silhouette tend to fit a wider range of body shapes comfortably. Our women's costumes collection includes plus size options alongside standard sizing so you can compare styles side by side.

Comfortable styles for a full night out

A costume that fits well through the shoulders and does not pull across the chest or hips will hold up far better across a long evening than one chosen on look alone. Looser dresses, tunics and separates give you room to move, eat and dance without adjusting all night. Check men's costumes for the wider fits available in classic character looks.

Couples and group costumes in your size

Plus size does not mean fewer options for coordinating with a partner or a group, since most classic pairs and themes are available across the size range. Pick a theme first, then confirm both people can find their size comfortably before committing to matching outfits. Browse couples Halloween costumes for pairing ideas that work at any size.
