Group Halloween costumes work best with a theme where each person buys their own piece rather than one shared bundle. Budget $30 to $70 per person. Each listing here shows a live retailer price so everyone in the group can order their own part from the same page.
Themes that scale. Pick the concept, then send everyone the piece that matches their part of it.
Choose a theme with an open cast list — an era, a colour, a movie universe, a profession — rather than a fixed set of characters. Open themes absorb late joiners and dropouts without breaking. The strongest group looks share one repeated visual element (same colour, same mask type, same silhouette) with individual variation on top.
Never buy a group's costumes on one person's size judgement. Send everyone the same product link and let them pick their own size and pay their own way — it avoids returns and awkward reimbursement. If someone is outside the standard size range, keep the shared element (mask, wig, colour) and let them source their own base garment.
Per-person cost usually lands between $30 and $70. Shared-accessory themes, where each person adds one item to their own clothes, drop that to $15 to $25 each and are far more likely to actually get worn.
Groups need the longest lead time because they move at the speed of the slowest orderer. Lock the theme three weeks out, share links two weeks out, and check in a week before. Late-October restocks are unreliable for matching items across multiple sizes.

Most complete looks land between $30 and $120 depending on the pieces involved. Prices shown here come live from the retailers, so use the price sort and budget filters to stay on target.
Each listing links straight to the retailer selling it — Amazon, Target, Walmart, Spirit Halloween, independent shops and more. Shipping speed and returns follow that retailer's policy.
Yes, if you order early enough for the retailer's shipping window. If you're within a few days of the party, browse the last-minute page for items that ship fast or come as simple kits.
