Have the most magical Halloween of all when you dress yourself or the kids up in a DIY unicorn costume. That's right, the trend of rainbow tails and glitter horns isn't going anywhere, and why should it? Dressing up as a unicorn on October 31 is pretty and easy. This is especially true when you go the homemade route and you're able to customize your look to your liking (yep, the more glitter, the better). Kids are also still totally obsessed with these mythical creatures, so it'll make getting dressed up for the big night a total breeze (especially if you're in need of a last-minute getup).
Below, you'll find unicorn costumes for adults, tweens, babies, and even infants. We have dresses, headbands, flower crowns, and more cute ideas that you'll love. Some of the looks require absolutely no crafting skills (hello, no-sew options), while others will allow you to put your sewing machine to work. Whichever you choose, it will look great and be totally comfortable. In fact, these costumes are so good, you might have just found a costume theme for the whole family.
Not into unicorns? No problem. We have DIY ideas for witches, princesses, and aliens!
