Costume Size Guide FAQs

How do I choose the right costume size?

Always compare your body measurements with the size chart provided on the product page. If you're between sizes, consider whether you prefer a looser or more fitted costume and whether you'll be wearing clothing underneath.

Are Halloween costumes true to size?

Costume sizing can vary depending on the manufacturer. We recommend checking the measurements shown on each product page rather than relying solely on your usual clothing size.

What should I do if I'm between sizes?

If you're between two sizes, choosing the larger size is often the most comfortable option, especially if you plan to wear extra clothing underneath.

Do children's costumes use UK sizes?

Most children's costumes are based on age ranges together with approximate body measurements. Always check the size guide provided on the product page before ordering.

Do men's and women's costumes fit differently?

Yes. Our men's fancy dress costumes and women's fancy dress costumes are designed using different sizing and measurements. Always refer to the relevant size chart before ordering.

Should I measure myself before ordering?

Yes. Measuring your chest, waist, hips and height before ordering is the best way to select the correct costume size and avoid disappointment.

Do different costume brands have different sizing?

Yes. Costume sizing can vary slightly between manufacturers. That's why we recommend checking the measurements on each product page whenever possible.

How do I measure my chest for a costume?

Measure around the fullest part of your chest while keeping the measuring tape level and comfortably snug. Compare your measurement with the size chart provided for the costume you're interested in.

How do I measure my waist?

Measure around your natural waistline, usually the narrowest part of your torso. Avoid pulling the tape too tightly, as this may affect the accuracy of your measurements.

How do I measure my hips?

Stand with your feet together and measure around the fullest part of your hips. This measurement is especially important when choosing women's and children's costumes.

Do costumes stretch?

Some costumes contain stretchy materials, while others have little or no stretch. Always refer to the product description and size guide for the best indication of fit.

Are shoes and accessories included with costumes?

Not always. Some costumes include selected accessories, while others are sold separately. Please check each product description carefully to see exactly what's included.

Can I exchange a costume if the size isn't suitable?

Please see our Refund Policy for information about eligible returns and exchanges. If you're unsure about sizing, we recommend contacting us before ordering.
