Best, Easy Last-Minute Halloween Costumes & Party Supplies 2020

Some Easy, Last-Minute Halloween Costume & Decor Ideas, Because You’re Not The Only One Scrambling

October 17, 2019 Updated February 1, 2021


It’s been *a year* so, if you find yourself struggling to put together some kind of semblance of Halloween 2020 and you’re down to the wire, we’re here to help. Also, just so you know, Amazon Prime will be your best friend right now, because most likely, you’ve got to get all these last-minute Halloween costumes and supplies shipped ASAP. We’ve also included other choices (in case you’ve got 1 week+ left), because Etsy and Michael’s have some really cute stuff this year, and we feel like we’d be doing a major disservice by not providing you with inspo.

So, fret not, Mama! Here are all the best last-minute costumes, party supplies, and home decor you can still get for Halloween 2020.

Best Baby Halloween Costume Ideas 2020

Disney The Child Costume Bodysuit for Baby – Star Wars: The Mandalorian

If you’re part of a big Star Wars/Mandalorian-loving family, you should totally dress your BB up as Baby Yoda, aka The Child. Not only was Baby Yoda the best thing to have happened to us in late 2019, but we’re also getting a Season 2 of The Mandalorian in October, so we might as well fully lean into it. This costume comes with a soft fleece-trimmed onesie and Baby Yoda cap.

Carter's Baby Halloween Avocado Costume

Avocados are in high demand because they’re delish and taste better than butter on toast. Evidently, avocados are also adorable as Halloween costumes, so if your baby is going to pose as a fruit this year, you might as well make it this little green guy from Carter’s. Complete with avocado jumpsuit, white long-sleeved shirt, and green striped socks, it’s all you avo wanted for your baby’s Halloween costume. 

$49.90 AT AMAZON

This Cuddly Bear Costume for toddlers is so aw-dorable, with black, white, and red plaid bow and ears. Cozy for naps, and classic for photos, this is one Instagram-worthy ensemble your feed — er, child needs.

Disney Woody Toy Story Stretchie for Baby

There will be no snakes in this cowbaby’s boots this Halloween — seeing as how footwear is attached to the rest of the getup.

We have no doubt that this is the Halloween costume for toddlers will be high in demand because let’s face it, these people know their customer (who, by the way, isn’t you).
