If you still haven’t found your Halloween costume yet, there’s no need to freak out. There’s still time to pick up a last-minute Halloween costume. Skip the long lines at the party stores and order your costume online instead. We’ve sorted through hundreds of options online and found lots of easy-to-order (and easy-to-wear) costumes. Best of all, every costume on this list is available through Amazon Prime, with most being eligible for two-day and even next-day shipping. Fast shipping means you can actually wait until the last minute to order (though we don’t recommend it).
Unlike other ho-hum Halloween costumes, these bad boys come with everything included in the picture. That’s right! While some “costumes” only come with only a vest, a tunic, or even just a wig, these costumes feature everything you need to turn a few heads. No other makeup, weapons, or bulky accessories are required.
But while all these last-minute Halloween costumes are all available for delivery by October 31, you’ll need to remember to choose either next-day pickup or two-day shipping at checkout if you want time to take a look and try it on before the big night. You may want to hurry, though, as specific sizes and styles are selling out fast. The longer you wait, the less likely you are to receive your costumes by October 31, so don’t procrastinate any longer!
Keep reading to see the best last-minute costume ideas for Halloween 2021, all of which are available with two-day shipping thanks to the magic of Amazon Prime.
