FAQ — adult costumes online

How do I get the right size?
Every adult costume has a size chart on the product page with chest, waist, hip and length measurements. Costume sizing runs different to regular clothing — always check the chart, don't just assume your usual size. If you're between sizes, size up.

Do you stock plus-size adult costumes?
Yes — we have a dedicated plus-size range with hundreds of styles. Plus-size costumes from Costume Crazy are designed to actually fit and flatter, not just be a bigger version of the standard.

How fast is delivery?
Most orders ship same or next business day from our Sydney warehouse. Standard delivery to most Australian metro areas takes 2-5 business days. Express shipping is available at checkout for tighter deadlines.

Can I get a costume in time for a party this weekend?
Often yes — order express and most metro addresses get delivery within 1-2 business days. If the deadline's really tight, get in touch and we'll do what we can.

Do you stock costumes for couples or groups?
Yes — we have matching couples costumes, group costume themes (Mario Bros, Power Rangers, classic horror cast, Spice Girls), and party packs for hens, bucks and birthday events.

Are the costumes good quality?
We stock a range. For one-off party use, our budget options are great value. For costumes you'll wear repeatedly or want to look really sharp in, our premium range uses better fabrics and construction.

Are your licensed character costumes the real thing?
Yes — most Marvel, DC, Star Wars and Disney costumes we stock are officially licensed. Each product page indicates whether the costume is licensed or an inspired-by alternative.
