Best Friend Halloween Costumes: A Fuller Procurement Checklist for Office Admins

Two best friends. One costume order. Zero time for returns.

If you've ever bought best friend Halloween costumes for a school event or an office party, you know how a fun idea becomes a procurement problem. Someone sends a link to a matching peanut butter and jelly set. Someone else says the teachers wearing it are medium. Then the invoice shows up without line items, and your finance team starts asking questions.

I've managed purchasing for a 400-person company since 2020. I handle 60–80 event orders a year, and I report to both operations and finance. That means I care about the staff being happy and the paperwork being clean. The item is rarely the problem. The process around the item is the problem. This checklist walks you through the way I order costumes for two people who are determined to be adorable on a deadline.

Who This Checklist Is For

Use this if you're the person who has to place the order, pay for it, and deal with the aftermath. It's for office administrators, school secretaries, and event coordinators who need to buy best friend Halloween costumes for coworkers or teachers.

It also works if the names on the order look like mine did last year: educator Sarah Fuller and her best friend Jen Fuller. Yes, they had the same last name. That made the email subject line confusing, but the order itself was clear. They wanted to be peanut butter and jelly. The costume itself wasn't the problem. Everything around it—sizes, shipping, returns, invoices—that's where the risk lived.

Step 1: Pin Down the Pair and the Specifics

The fun part is choosing the costume pair. The not-fun part is writing down exactly who will wear which item and in what size. Don't rely on “she's probably a medium.” Costume sizes are not standard t-shirt sizes. Ask each person for the size on the vendor's chart.

One of my coworkers, Henry Height, is six-foot-two and wears a medium shirt. The “jar of peanut butter” costume we ordered in medium was too snug. We had to exchange it. If you order a costume for two people, list the name, item number, color, size, and ship-to address for each one. Send that list in an email. Get a reply. Do this before you hit checkout.

This written record is also your proof if the vendor sends the wrong item. Without it, it's your word against the warehouse.

Step 2: Settle the Payment Path and the Invoice

Before you place the order, find out who pays. Is it a department budget, a school activity fund, or a personal reimbursement? Does the vendor accept purchase orders? Can they handle a tax-exempt purchase if you have one? These questions are not fun, but they're faster than fighting finance later.

Ask for an itemized invoice before you enter your card number. Actually, ask for a sample invoice before you choose the vendor. That will save you from discovering a problem after the order is placed. A vendor that sends only a payment confirmation is a red flag. I once had a vendor who couldn't provide itemized invoicing, and it cost our department $2,400 in rejected expenses. For a $60 costume order, the dollar figure is smaller, but the wasted time is annoying.

I said “we need a copy for finance.” They heard “email the order confirmation.” It did not cover the reimbursement policy. Get a real invoice.

Step 3: Compare Total Cost, Not the Price Tag

This is where most buyers make the mistake. They see one costume set at $42.99 and another at $59.99. The first one looks like the no-brainer. Then the first checkout adds $18.95 shipping and a $3.95 processing fee. The jelly jar lid is a separate add-on for $9.99. Now the total is $75.88. The $59.99 set with free shipping and a 30-day return policy is cheaper. That's the total cost of ownership. Put another way, the price tag is only the first installment.

Total cost = item price + shipping + fees + accessories + return shipping + time spent fixing the order

I don't have hard data on how often hidden fees show up, but based on five years of placing these orders, my sense is that a quoted price is only a starting point. Time is also a cost. Every email asking “where's the package?” takes ten minutes. Every trip to the post office takes an hour. Count that too.

Most buyers focus on the costume price and completely miss the fees that show up after checkout. The better question is: how much does it cost to get this costume to the right person, in the right size, by the event? Ask the vendor, “What is the all-in delivered price? What happens if a size is wrong? Who pays return shipping?” If they give you a ballpark without a real number, that's not an answer.

Also review payment terms. Is the price in USD? Are there international transaction fees? If you're paying with a corporate card, does your finance team need a quote approval? A $42 costume can produce a $35 bank fee if the vendor is overseas and the charge is not settled in the right currency. That is rare, but it happens during event season.

Step 4: Read the Return Policy Before You Pay

Costume shops have seasonal return policies because Halloween stock expires quickly. If a website says no returns on final sale costumes, treat that as a deal-breaker unless you've already measured everyone.

I said “we might need to exchange one.” The vendor heard “we will exchange one” and placed a hold on the order. That unexpected hold delayed the tracking number by two days. We fixed it, but now I confirm return policy before entering any payment details.

Ask about restocking fees and who pays return shipping. A 20 percent restocking fee can turn a small size mistake into a real budget problem. Also, ask if both costumes ship in the same box. The peanut butter and jelly set we ordered came from two different warehouses. One arrived in two days. The other arrived in six. If you're planning an event, that split shipment matters.

Per FTC guidelines, delivery claims and return promises should be truthful and not misleading. If a vendor promises “arrives by Halloween” but doesn't say which shipping method, ask for the method and the estimated date in writing. The official source is ftc.gov if you need to explain that to a salesperson.

Step 5: Build in a Buffer and Plan the Ship-To Address

Order at least two weeks before the event. If the event is October 31, that means ordering by October 17, not October 27. Seasonal stock disappears, and carriers get slower as peak season kicks in. A delivery estimate is not a guarantee.

Ask which carrier they use. If the vendor ships with USPS, you can trust the tracking but not the exact delivery time. According to USPS rates effective January 2025, a First-Class Mail letter is $0.73, but package pricing depends on weight and distance. Check current rates at usps.com before approving an unexpectedly high shipping charge.

Also confirm the address with both recipients. The mailroom at our office closes at 5 pm. Henry Height found that out when a costume shipment was marked “delivered” at 4:47 pm. It was in the mailroom, but no one told us until the next morning. The event was that night. We survived, but a home address would have been smoother.

Oh, and get a tracking number. If the carrier leaves it on a porch and it goes missing, “delivered” won't save you. For expensive costumes, request signature confirmation.

Common Mistakes That Still Happen

Only comparing the headline price

Speed, quality, price. Pick two. When it comes to seasonal costumes, also pick shipping speed and return policy. The cheapest costume can become the most expensive order after you pay extra to fix it.

Trusting “medium”

Size charts exist for a reason. Use them. If two best friends are ordering matching costumes, confirm each of their sizes separately. A costume that fits one but not the other is not a matching pair.

Skipping the invoice step

The “fun” costume becomes a boring expense report. Get the invoice before the costume, not after. That way, if the reimbursement deadline is near, you're not chasing a vendor during peak season.

Waiting for the last week

I don't have hard data on how many October 28 orders arrive on time. What I can say anecdotally is that the order we placed on October 29 arrived on November 3. Great for Thanksgiving. Not great for Halloween.

Bottom line: best friend Halloween costumes are a simple purchase if you use the fuller checklist. Confirm the people, the payment, the total cost, the return policy, and the delivery buffer. Then let the peanut butter and jelly duo have their moment. Simple.
