FAQ — costumes in Sydney

How fast is delivery to Sydney?
Most orders ship same or next business day from our Sydney warehouse. Standard Sydney delivery is 1-3 business days, with express options available at checkout for tighter deadlines.

Do you have a physical store in Sydney?
We're an online-only retailer — no retail shopfront. Warehouse pickup may be available on request for Sydney customers, especially around peak periods like Halloween. Get in touch and we'll let you know if it's an option for your order.

What's the biggest event for costume hire in Sydney?
Halloween (late October) is the busiest, followed by Book Week (late August). Sydney also has strong demand for Mardi Gras (February-March), Oktoberfest (late September-October) and Christmas costume events (December).

Should I buy or hire a costume?
For most events, buying makes more sense than hiring. Our budget costumes often cost less than a hire fee, you keep them for next time, and the range online is much bigger than any local hire shop. For premium one-off needs (like a high-end Santa suit for paid event work), the cost-per-use over multiple years works out well below hire prices.

How do I get the right size?
Every product page has a size chart. 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. Costumes are usually easier to take in than let out.

Can I return a costume if it doesn't fit?
Yes — get in touch and we'll arrange a return or exchange. We just need the costume back unworn with original packaging.

Do you stock licensed character costumes?
Yes — officially licensed costumes from Marvel, DC, Star Wars, Disney, Harry Potter, Monster High and other major franchises. Each product page indicates whether the costume is licensed or an inspired-by alternative.
