Onesies

Low Cost Onesies: Onesie costumes to make your dress up party the most comfortable ever!

Winter is coming, and there's no better way to keep warm than with a comfy Onesie

At Blossom Costumes, we stock a wide range of adult onesies for men and women. With a variety of themes and characters to choose from like Pikachu from Pokemon, Tigger and Winnie The Pooh to cute and comfy animals like zebras, unicorns and leopards.

You will be so spoilt for choice, but once you have made your decision and ordered your onesie online with Blossom, you probably will never want to take it off (especially when the temperature drops)!

Comfortable costume onesies for men and women

At Blossom Costumes, we try to ensure that all of the costumes we sell are comfortable (and yes, that even includes our extensive range of corsets). However, there's nothing in stock more comfortable than a onesie. These onesies make the softest dressing gowns look like straight jackets made of sandpaper.

They're perfect for a costume party, or even just for lounging around the house. And hey, if you have a very permissive workplace, you could even try wearing it there. These onesies come in a variety of different sizes, and their loose fitting silhouettes are perfect for both male and female physiques.

Onesie costumes for children

When you're buying a costume for a kid, thrift dictates that you want something that can be used several times. Unlike adult costumes, children will grow out of their costumes promptly — and might only last for a single Halloween!

The joy of the onesie costume is that it can be worn around the home again and again. These onesies for kids are comfortable, great looking and an absolute bargain when you think about how reusable they are.

Our Onesies:

• Are made from high quality new materials
• Come with free shipping if the order is over $30
• Cute, warm and cuddly soft fleece
• And come in a range of sizes too

We also have extra animal slipper-shoes in a range of colours to match your new onesie, so order both at the same time!

Sizes for everyone, XS to XXXL

Finding a onesie that actually fits shouldn't be the hard part. We stock our onesies across a wide size range, from small right through to XXL, XXXL and 4XL, so a bigger build doesn't mean settling for something too snug. (Confirm and state your actual size range here, including whether it's unisex sizing.) Check the size guide on each product page to find your best fit before you order.

Monster-mash onesies

Fancy something a little more roar than cute? Our monster-themed onesies bring big, bold, larger-than-life energy to your next dress-up night or lazy Sunday. (Add link to your monster/Monsters Inc-inspired onesie products if in stock.)

Silly, funny, and downright novelty

Not every onesie needs to be a specific character. If you're after something that's just plain fun, an oversized, exaggerated, or novelty-style onesie is guaranteed to get a laugh at the door, no character recognition required. Perfect for a silly costume party, a group theme, or just embracing your inner goofball on the couch.

Why choose Blossom Costumes for your onesie
