Halloween is one of the busiest shopping seasons of the year, but few businesses experience the rush quite like HalloweenCostumes.com. Based in Minnesota, the family-founded company has grown into a global costume retailer capable of handling as many as 120,000 orders on peak days. Behind those numbers is a massive operation involving hundreds of thousands of square feet of warehouse space, extensive inventory systems, creative costume designers and elaborate animatronic creations. From its humble beginnings with homemade costumes to its expanding fulfillment network, the company offers a fascinating look at the enormous amount of work that goes into getting Halloween ready for millions of customers.
A Family Costume Business Grew Into a Global Halloween Retail Giant
What began as a mother’s homemade Halloween costumes eventually turned into one of the world’s largest online costume retailers. The story of HalloweenCostumes.com starts with Tom Fallenstein, whose mother, Jenice, was a talented seamstress who made costumes for her family. One outfit in particular, a Super Mario 3 costume, left such an impression on Tom that it helped spark an interest in the Halloween business. The family initially began renting out its handmade costumes to people in their community, but demand gradually grew beyond what a small home-based operation could handle. In 2001, Tom launched an online store, allowing the business to reach customers far beyond Minnesota. What followed was a remarkable expansion from a small family operation into an international retailer serving customers in approximately 100 countries. The company now operates under the FUN.com business and sells thousands of costume styles, accessories and seasonal products. Its growth also reflects how online shopping transformed Halloween retail, allowing customers to find everything from familiar superhero outfits to unusual novelty costumes without visiting a traditional costume shop.
Its Massive Warehouse Network Has More Than 500,000 Square Feet of Space
Handling millions of costumes requires considerably more than a few storage shelves and packing tables. HalloweenCostumes.com has expanded its facilities dramatically over the years, growing from its beginnings at the Fallenstein family home to a warehouse operation covering hundreds of thousands of square feet. Tom Fallenstein described the company’s expansion from 10,000 square feet to 50,000 square feet before eventually reaching more than 500,000 square feet across its operations. Its Minnesota headquarters in the Mankato area is a major part of that network, supported by a substantial fulfillment facility in Kentucky. The company’s 2026 headquarters tour materials describe approximately 180,000 square feet of warehouse space in Minnesota and another 280,000 square feet in Kentucky. Inside the Minnesota facility, visitors can see dozens of warehouse rows, extensive inventory storage, conveyor systems, picking locations and packing stations. Some rows contain as many as 20,000 costumes, giving an idea of the sheer quantity of products the business must organize. Forklifts, warehouse employees and specialized equipment work together to move products through the facility. The Kentucky location provides additional storage and shipping capacity, helping the retailer distribute orders across a wider geographic area.
The Company Handles an Extraordinary Surge of Orders During October
Halloween may fall on just one day, but the shopping rush creates months of intense activity for costume retailers. HalloweenCostumes.com reportedly handles as many as 120,000 orders on its busiest October days, an extraordinary volume for a business operating from Minnesota. The company has previously explained that approximately 80% of its annual sales occur during the three months leading up to Halloween, making seasonal preparation essential. Its 2026 headquarters tour materials estimate that roughly four million orders are shipped annually, with approximately 2.5 million concentrated in October. The Minnesota operation accounts for an estimated 44,000 orders on peak days, while its Kentucky facility handles around 67,000. These figures illustrate why the business needs multiple fulfillment locations rather than relying entirely on one warehouse. The company also uses Amazon Multichannel Fulfillment to provide additional storage and shipping capacity during periods of exceptional demand. Its earlier fulfillment data showed that the retailer could handle an increase from approximately 6,000 daily orders during quieter periods to as many as 100,000 during peak season. Meeting this demand requires careful inventory planning, seasonal staffing, automated order processing and coordination between warehouses. Even a small delay can affect thousands of customers hoping to receive their costumes before Halloween.
It Designs Its Own Costumes and Creates Elaborate Animatronics
Behind the enormous warehouse operation is a creative business that does considerably more than store and ship costumes. HalloweenCostumes.com has its own product development and design teams, which work on ideas inspired by entertainment, popular culture and customer interests. Developing a costume can involve several stages, including concept art, fabric selection, pattern creation, sewing, painting, photography and quality checks. The company also works with licensed entertainment properties, allowing it to produce costumes and decorations based on recognizable characters and franchises. Its product range extends from traditional Halloween outfits to unusual requests, including novelty costumes shaped like everyday objects. The company has also developed its own animatronics, which are mechanical Halloween decorations designed to move and create theatrical effects. Licensing agreements allow it to produce elaborate figures based on well-known fictional characters, including versions of Hollywood monsters and characters such as Heath Ledger’s Joker. Its 2026 headquarters experience even showcased a nearly 14-foot Balrog inspired by The Lord of the Rings, demonstrating the scale of some of its creations. The company also uses 3D printing and prototype development as part of its creative process. These activities help explain why HalloweenCostumes.com operates more like a combination of a costume design studio, entertainment workshop and major fulfillment business than a conventional online retailer.
