Our Halloween floor in Marietta — come try it on
Shop early for the best selection. Popular costumes and common sizes sell through fastest in October. If you already know what you want, September is the best time to come in — and if you're shopping last-minute, come anyway. We're usually the ones who can still help.

Why Buy Your Costume in Person
There are things a website can't do for you two weeks before Halloween.
Try It On First
Costume sizing is inconsistent between brands. Trying it on beats guessing — and beats waiting for a return that won't arrive in time.
Take It Home Today
No shipping windows, no delivery estimates, no tracking numbers. Walk in, walk out with the costume.
Real Help From Real People
Tell our team your idea and they'll pull pieces together, suggest accessories, and tell you honestly what works.
Last-Minute Rescue
Costume didn't ship? Plans changed? Party tonight? We're open 7 days a week and this is exactly what we're here for.
See the Real Colors
Photos lie about color and fabric. Seeing a costume in person tells you what you're actually getting.
Everything in One Trip
Costume, wig, makeup, accessories, decorations, candy bags, and party supplies — one stop instead of five.
However You're Celebrating
From trick-or-treating to office parties, we've got the night covered.
Serving Metro Atlanta Since 2016

Halloween FAQ
Do you sell Halloween costumes year-round?
Yes. We carry a wide selection of costumes for kids and adults all year, along with wigs, masks, makeup, and accessories. Our Halloween selection expands significantly starting in late summer.
When is the best time to shop for a Halloween costume?
September through early October gives you the best selection, especially for popular themes and common sizes. That said, we stay stocked through Halloween and are often the store that can still help when other options have run out.
Can I try on costumes in the store?
Yes — and we recommend it. Costume sizing varies a lot between brands, so trying it on is the difference between a costume that works and one that doesn't. Our team can help you find the right fit.
Do you have costumes for kids and adults?
Both, plus teens and toddlers. We carry classic and scary looks, superheroes and villains, pop-culture themes, funny costumes, and couples or group options. We also have pet costumes.
Do you carry wigs, makeup, and accessories?
Yes. Wigs in every color and style, special-effects makeup, fake blood, prosthetics, face paint, colored contacts, masks, hats, capes, gloves, and props. It's often the accessories that make a costume work.
What are your hours during Halloween season?
We're open 7 days a week: Monday–Friday 10am–7pm, Saturday 9am–7pm, Sunday 12pm–5pm. We extend hours closer to Halloween — call 770-734-3950 to confirm.
Do you have Halloween decorations and props?
Yes — spider webs, tombstones, skeletons, animatronics, lighting, yard décor, and indoor decorations. We also rent fog machines, and we can create Halloween balloon décor for parties.
Can you do Halloween balloon decor for a party?
Yes. We design, deliver, and install Halloween balloon garlands, arches, and columns throughout Metro Atlanta. See our balloon decor page or call 770-734-3950.
Where exactly are you located?
2550 Sandy Plains Rd #200, Marietta, GA 30066, in the Sandy Plains Village shopping center — easy access from I-75 and I-575, with parking out front.
Is it too late to find a costume the week of Halloween?
Not at all. Selection is thinner on popular sizes, but we restock through the season and our team is good at putting together a look from what's on the floor. Call ahead at 770-734-3950 and we'll tell you honestly what we have.
