Very soft and feels almost like real hair,” wrote one happy customer.

Channel some scary-sultry energy as Emily from Corpse Bride. This dress, headband, and glove set pretty much has you covered, but investing in a wilted bouquet and white shoes will help take this look to the next level. Of course, trying your hand at some Tim Burton-esque makeup will really give you that rotting bridal glow.

Sometimes dressing up for Halloween is as simple as throwing on a onesie. This adorable Lilo & Stitch-themed onesie has a rating of 4.3 out of 5 stars based on over 7,000 reviews so you know it’s legit.

If you’re still thinking about Euphoria Season 2, why not spend Halloween night in one of the most iconic looks from the series? Pair this gingham top with a floral minidress and sparkly heeled boots to look just like Cassie during *that* bathroom meltdown. If you get the country glam hair and makeup, plus Cassie’s look of total desperation just right, you’re sure to bring big Oklahoma energy.

The most low maintenance costume on this list is also the most customizable. Since you’re establishing your costume from the neck up, you can wear anything you want as long as it’s blue and, preferably, has some cookie crumbs on it. In fact, the most important accessory for this stress-free Cookie Monster costume is a cookie, so as long as you have that, you’re golden. Er, actually blue.

Who can forget the stylish Beauxbatons Academy of Magic uniforms from Harry Potter And The Goblet of Fire? Originally presented as a competing school during the Triwizard Tournament, Beauxbatons’ most iconic student is Fleur Delacour. As you’d expect, given it’s hefty price tag, this ensemble has everything you’ll need to dress as Fleur, including her prim little hat.

Want to go for a more obscure look while still repping the Harry Potter franchise? Try dressing as a Cornish Pixie. First spotted in Harry Potter and the Chamber of Secrets, these electric blue pixies have shimmering wings, pointy ears, and a bit of an addiction to mischief. These gauzy fairy wings are a great Cornish Pixie costume centerpiece. From there, you can add elfin ears, antennae, blue body paint...the sky is the limit.

If you’ve been waiting patiently for the sequel to Avatar, this Neytiri dress from FringeGeek on Etsy is a great way to express your excitement for what’s sure to be the movie event of the year. (Sorry, Top Gun: Maverick.) Adding some iconic Na’vi ears, a tail, and some body paint will take this blue Halloween costume to new heights.

Looking for a low effort and comfy costume this Halloween? Enter Violet Beauregarde from Charlie And The Chocolate Factory. This two-piece velour jogging set is a dead ringer for the one AnnaSophia Robb wore in the 2005 remake of the sinister candy-themed film. Just add bubble gum and a sense of entitlement.

Remember those fairy wings from earlier? If you don’t want to be a Cornish Pixie, you could always use those wings to be the Blue Fairy from Pinocchio instead. This light blue maxi dress can be worn on its own or with a blue shawl to pull the ‘fit together. Don’t forget your blue headband, a magic wand, and a ton of sparkles, you know, for realism.

Ready for a major throwback? Try pairing this highly-rated blue Peter Pan collar dress with a rounded straw hat, white crew socks, and Mary Janes to look like Madeline, the brave, Parisian protagonist of Ludwig Bemelmans’ 1939 book of the same name. This costume is simple to put together but gives off effortlessly chic vibes, and is a fun conversation starter for fans of Madeline.
