Harry Potter Costumes for Adults
Dress as everyone’s favorite wizard this Halloween. If you want an easy Harry Potter adult costume, check out this one, which is modeled after the Hogwarts uniform. It includes a gray V-neck sweater with an “H” embroidered on the chest, a white collar (not a whole shirt), a red and yellow striped necktie to mimic Gryffindor colors, round black glasses like the ones Harry wears, and a wand.
If you want to don a more “official” Harry Potter costume, then here’s how you do it. You need a white button-down shirt (your own). Add this Harry Potter tie, an officially licensed Harry Potter costume accessory. This 100% silk Gryffindor tie is 56 inches long and 3.8 inches wide, with the Gryffindor house crest at the bottom. When Halloween is over, wear it to work!

Next, add a Hogwarts robe. Nothing pulls a Harry Potter costume together more than the Harry Potter robe — the most important part of the costume. This is not the place to skimp on a Harry Potter costume, because it’s the part everyone will notice. Instead, get yourself this officially licensed, authentic Hogwarts robe. This deluxe Gryffindor robe bears the Gryffindor seal and has lined sleeves, a lined hood, and a hidden wand pocket. This replica is just like the robe from the movies, making you a true Gryffindor.
To complete the costume, add Harry Potter glasses and a wand.
Optionally, you can add a Harry Potter Gryffindor scarf, which might be a nice if you’re somewhere that’s chilly on Halloween night. Plus, you can get a lot of wear out of this scarf even when it’s NOT Halloween. Wear this officially licensed Gryffindor scarf all winter long.
Hermione Costume for Adults
An adult Hermione costume is probably the most popular Harry Potter costume for grown-ups. Ladies love to dress up in a sexy Hogwarts costume, and there are several sexy Hogwarts outfits to choose from.
You’ll get lots of compliments in this sexy Hermione costume. It’s great for college Halloween parties and club parties. Older women get a kick out of it too.
This sexy Harry Potter costume is not for the timid. The flirty minidress has a deep V-neck definitely shows cleavage. It’s fitted at the bust, but loose where ladies need it to be — in problem areas like the tummy and hips. Made of a stretchy polyester, this Hermione sexy costume fits true to size. The short Velcro cape covers your arms and will help keep you warm on Halloween night. This “Wizarding Wanda” costume also includes a collar and necktie in Gryffindor colors, glasses and a wooden wand. This adult plus size Hermione costume comes in 1X/2X and 3X/4X.
Depending on how sexy you want to go (or how tall you are, or how much dancing you want to do), you might want to add some boy shorts, hot pants, tights (fishnet or otherwise) or leggings underneath for modesty.
For the shoes, add mary janes if you want the innocent “tease” effect, or add black leather boots or sexy heels if you want to go all out “vixen.”
Sexy Hermione Costume
Here’s another Hermione sexy Halloween costume. If you’ve already worn Wizarding Wanda, then try this costume instead. For those who aren’t picky about it being an authentic costume, this is a sassy, fun option.
This adult Hermione costume looks like a two-piece, but it’s actually a dress with a pleated skirt bottom. It definitely has that sexy schoolgirl feel to it. It fits true to size, and the stretchy poly Lycra material makes it flattering and forgiving.
The Hermione outfit has a “Gryffindor-esque” crest on the chest, and comes with collar and necktie, wand, and wizard hat.
<<< Great news! Voluptuous lady wizards of all sizes can also have the chance to turn heads in this costume. Get the plus size sexy Hermione costume in sizes 1X/2X or 3X/4X.
I’ll repeat the warning about the dress length — wear boy shorts underneath if you’re concerned about it.
Traditional Hermione Granger Costume for Adults
If you’re wondering how to dress like Hermione Granger for Halloween if you don’t want to be sexy or slutty, here’s another Hermione costume idea — one that requires you to collect components from a few different places. (Think of it as seeking horcruxes.)
Order this Gryffindor house sweater and tie, add a gray pleated skirt (try Lands’ End for adult school uniform skirts), and add the Gryffindor robe featured above. Cap it off with Gryffindor scarf and wand.
To mimic Hermione’s hair, brunettes can add some big curls with a 1-inch curling iron. Blondes and redheads can get a long, curly wig. (Or, add a red wig and make it a Ginny Weasley costume.)
Hermione’s Yule Ball Outfit
For something totally unique, you can also wear Hermione’s Yule Ball Dress from Harry Potter and the Goblet of Fire. Read our complete guide on how to get Hermione’s Yule Ball look.
