Back in 2020, Severance fans had to DIY everything for Halloween. Sew their own green badges. Paint blue reflection patches on thrift store vests. Now, with the Severance Merch Store, you can pull together a Lumon-appropriate costume using pieces you'll actually wear year-round. Here are the best Severance Halloween costume ideas using official fan merch.

Why Severance merch makes great costume pieces
The Severance aesthetic is built on corporate monotony: blue suits, pale button-ups, and those green and black MDR badges. The merch line directly reproduces those key costume elements with quality materials. Each piece is designed for everyday wear, so you're not buying a single-use costume. A Lumon sweater works just as well for a Halloween party as it does for a Sunday coffee run.I've found that the best costumes come from layering recognizable accessories. A single MDR badge on a blue collared shirt instantly reads "Lumon employee." The merch store sells individual badge pins ($12) that are screen-accurate replicas. Combine one with a dark blazer from your closet, and you've got a costume that took ten seconds to assemble.
Using the Lumon sweater for your Halloween look
The Lumon Knit Sweater is the star of the collection. It's a heavy-knit pullover with the Lumon logo centered on the chest. The fabric weight (350 gsm) means it holds its shape well, even after layering over a collared shirt. Wear it with dark slacks and the badge pin for a dead-on Helly, Mark, or Irving costume.How to style it for different characters
- Helly R: Tuck the sweater into a high-waisted A-line skirt. Add the badge and a scowl. Bonus points for carrying the Lumon mug.
- Mark Scout: Layer a white button-up under the sweater, leaving the collar out. Pair with chinos and dark sneakers. The slightly rumpled look sells it.
- Irving: Wear the sweater over a black turtleneck. Add a flat cap if you have one. The key is a serious expression and a coffee mug.
The sweater comes in sizes XS-3XL. I recommend sizing up if you plan to wear it over another layer. Standard shipping is 5-10 business days within the US, so order ahead of Halloween.
Adding props with desk collectibles
The Lumon Desk Mug and Water Bottle Set are the perfect props. The mug is ceramic with a printed logo, and the water bottle is BPA-free plastic with a sports cap. Both are designed to look like they came straight from a severed floor work station.For a more immersive look, grab the MDR Pen Set ($15). It includes four pens in different colors, just like the ones Dylan, Mark, Helly, and Irving use. Clip one to your shirt pocket or badge lanyard. These small details make the difference between "Oh, are you from that show?" and "COBEL!"
Putting together a group costume
Group costumes are where the merchandise really shines. The MDR Group Pack gives you four mini badge sets and four pens. Pair each with a blue button-up from any department store. One person can be Helly, another Mark, etc. Add the Lumon sweater for the manager figure (like Milchick) or a black outfit for the security room attendant (Graner).If you want a non-MDR character, grab a Lumon baseball cap ($25). Wear it casually with the sweater for a "Lumon employee after hours" look. Or, for a Mrs. Selvig costume, use the canvas tote bag and fill it with baked goods (real or fake).
Care tips for your merch after Halloween
These pieces are designed for daily wear, so treat them like real garments. The sweaters should be washed inside out in cold water, then laid flat to dry. Do not machine dry - the logo can crack. The mug and water bottle are dishwasher safe, but hand wash the mug to preserve the print. Badge pins can be stored on a corkboard or in a drawer. If you plan to wear the sweater again for another event, store it folded (not hung) to avoid stretching.Frequently Asked Questions
