Halloween 2026 Falls on a Saturday

This year is the big one — Saturday 31 October 2026 means full-scale parties with no work the next day. Popular adult sizes sell through earlier in Saturday years, so lock in your costume ahead of the final week. Weekday orders before 2pm ship same day from Melbourne, and Express Post covers most metro areas in 1–2 business days.

Couples, Groups and Work Parties

Dressing as a duo or a crew? Couples and group costumes are the fastest way to a coordinated look — one theme, mixed characters. For office parties, funny and inflatable styles get the laughs without the gore, while classic scary characters never miss at a proper Halloween party.

Adult Halloween FAQ

What should adults wear for Halloween 2026? Scary classics — vampires, witches, zombies, devils — lead every year, with funny inflatables close behind for parties and work events. Pick by the event: full character for a Halloween party, easy throw-on or accessory-led looks for casual dos.

What sizes are available? Standard adult sizing runs S–XXL with a dedicated plus size range up to 3XL. Most costumes are designed to wear over clothing, so size up when in doubt.

How late can I order? Order by 27 October with standard post or 30 October with Express Post for delivery before Halloween.
