Returns & Exchanges

About Oya

We understand that sometimes things don't work out as expected. That's why we'll do our best to accommodate your returns, and exchange requests and ensure a hassle-free experience. Here's the deal: Once you receive your order, you have a 14-day period to make any returns or exchanges. You can return your order to the Montreal warehouse. But remember, when the countdown to Halloween is on, and so is our FINAL SALE! The last 10 days before Halloween, all sales are Final Sales: No refund, but you can still be eligible for an exchange or credit memo.



This is how it works:

Here's what you need to know:

  • The 14-days period start from the date you receive the package. We don't include the shipping time. So you have 14 days from the receiving the package to ship it back to usFor warehouse pick up, the 14-day period start when the order is ready for pick up.
  • Item(s) must be new, unused and in their original packaging, along with all accessories. We can't accept returns on items that have been used or have those pesky deodorant smells or accidental makeup stains. Take a moment to check out our item restrictions below
  • There will be a 10% handling fee for return of 1 item, and 15% for 2 or more items. We waive all handling fees on item exchange.
  • Please keep in mind that we don't refund the original or return shipping charges. 
  • For peace of mind, we recommend using a traceable shipping method with delivery confirmation.

When you come by to pick up your costume, take a moment to inspect it and make sure it's the perfect fit. If you need a different size or want to exchange for another costume, we will do our very best to accommodate those exchanges on the spot. We can accommodate 1 exchange and it might take a bit of patience as we work our magic.  

If you are returning a costume for an exchange or return, remember the 14-day period start when the order is ready for pick up. To make your exchange experience smoother, check our website to make sure the size you need is in stock. This way, you can save yourself some valuable time. Don’t forget to write down the style number and size.  

After October 20, 2023, the Final sales also applies to warehouse pick up. Just keep in mind we still allow 1 exchange, but no Refund.

TRYING ON A COSTUME: When trying on a costume, we strongly recommend you do not try the accessories enclosed. This will limit the chances of accidental damage and will ultimately facilitate the exchange or return of the costume.

 INELIGIBLE ITEMS: If an item doesn't meet our return criteria, we can send it back to you if you give us the green light to charge your credit card for the applicable return fee. Otherwise after 30 days, it's time to bid farewell as we responsibly dispose of it.
