No Magical Family? No Problem!

Your kid doesn’t need a magical family tree or a vault at Gringotts to pull off top marks at Hogwarts—just ask Hermione Granger. Raised by two perfectly non-magical dentists, she still managed to master spells faster than most students with wizard blood to spare. That same spark of magical potential might be sitting at your kitchen table right now, and this Kid’s Deluxe Harry Potter Hermione Costume is the perfect first step toward a very enchanting future.

Whether you child is reciting potions theory or practicing her wand flicks in the hallway, this Made By Us outfit sets her up for straight-A sorcery from day one. It comes with everything she'll need to feel right at home during her first day at Hogwarts... or to make her feel like the most magical kid at the costume party.

Design & Details

This officially licensed Hermione Granger costume is inspired by the Hogwarts school uniform seen in the Harry Potter films. It starts with a full-length black robe lined in Gryffindor burgundy satin, complete with an oversized hood and embroidered house crest. The robe fastens in front with a loop and button, so it’s easy to slip on before heading to class—or just downstairs for dinner.

The costume also includes a gray v-neck sweater with a cardigan-style button-up front and a matching Gryffindor crest. A pleated skirt and shirt front recreate the iconic school look, and a satin necktie in gold and burgundy completes the uniform. Just add a wand and an eagerness to correct everyone's pronunciation of Wingardium Leviosa.

Hogwarts Awaits

From sorting ceremony day to every single library trip in between, this costume captures the clever, determined energy that makes Hermione such a standout. It’s ready for spell practice, book reading, and possibly saving the entire school—again.

Questions & Answers

Q: My daughter is a size 7/8 should I buy a small or medium? (1 Answer)
Asked by Lilly | 31 August 2025
Monster Responds...
A size 7/8 falls right between our Small (child size 6) and Medium (child size 8-10), so the Medium is likely the better fit. The Medium has a 33" sweater chest, a 26" skirt waist, and an 18" skirt length, while the Small measures 31" chest, 24" waist, and 17" skirt length. Comparing your daughter's actual chest and waist measurements to those numbers is the surest way to choose.

Q: Hi, how to take the robe’s length? Is it from the shoulder or the top of the head?
Thank you (1 Answer)
Asked by AD | 28 July 2025
Monster Responds...
The robe length is measured from the shoulder down, not from the top of the hood. On the size chart, that measurement runs from 37 1/4" for a size 4 up to 49 1/2" for a size 16, so you can compare it against your child's shoulder-to-floor measurement to find the best fit.

Q: Hello is this kids sizing? What would you recommend for a 7 year old soze (1 Answer)
Asked by Lou | 18 November 2024
Monster Responds...
Yes, this is a kids costume! For a 7-year-old, the Small (child size 6) or Medium (child size 8-10) could both be worth considering depending on your child's measurements. The Small has a 31-inch sweater chest and 24-inch skirt waist, while the Medium steps up to 33 inches and 26 inches. Comparing those numbers to your child's actual chest and waist measurements is the surest way to land on the right size, and sizing up is a good call if they fall between the two.

Q: What does the tag say about the clean instructions for all of the items in these costumes?
(1 Answer)
Asked by Sk | 28 October 2024
Monster Responds...
Care instructions aren't included in our copy for this costume, so the tag on each piece is the best place to check once it arrives. What we do know is that the main robe is 100% polyester and the sweater is 62% polyester and 38% acrylic, and general care guidance for those materials typically means machine wash cold and tumble dry low, but always follow what the tag says to be sure.

Q: Which size would fit best for my 7 year old. She is 62lbs and 50.5 inches tall. (1 Answer)
Asked by Tara | 1 October 2024
Monster Responds...
At 50.5 inches tall and 62 lbs, your daughter sounds like a great fit for the Small, which is sized for a child size 6, or the Medium, sized for a child size 8-10. The Small has a 24-inch skirt waist and a 39-inch robe chest, while the Medium steps up to a 26-inch skirt waist and 40-inch robe chest. Comparing her actual chest and waist measurements to those numbers is the surest way to land on the right size, and we generally suggest going with the larger size if she falls between the two.

Q: Is this costume treated with flame retardants? (1 Answer)
Asked by Anonymous | 3 October 2023
Monster Responds...
Flame retardant treatment isn't something we have details on for this costume. The main body is 100% polyester and the sweater is 62% polyester and 38% acrylic, and as a general note, polyester is naturally more resistant to ignition than many natural fibers, though that is not the same as a flame retardant finish. For specific safety certification questions, checking the physical care label that ships with the costume will give you the most accurate information.

Q: Hello. I saw a review saying the colouring on the robe is different from the tie. Has this been corrected? (1 Answer)
Asked by Tanya | 9 September 2023
Monster Responds...
We aren't able to speak to the history of individual reviews or past production changes, so I can't confirm whether a specific coloring issue has been corrected. What I can tell you is that this is an officially licensed Hermione costume, and the tie is described as a faux silk Gryffindor crest print, while the hooded robe features red satin lining on the sleeves and front edges, so the two pieces do use different materials and finishes by design.

Q: How this costume supposed to washed
(1 Answer)
Asked by Anonymous | 8 October 2022
Monster Responds...
Thank you for your question! Always follow the care instructions on the tag when available, otherwise, we recommend hand washing or spot cleaning and hanging it to dry. Please do not iron, instead, you would want to steam out wrinkles.

Q: Hi excuse me but the shirt come separated from the sweater or it comes knit with the sweater (1 Answer)

I appreciate you taking the time to ask this question. The shirt front is separate from the sweater.
