What robe should I use for Bob Ferguson’s costume?

Choose a red and navy cotton flannel robe with visible plaid lines; its stronger pattern still gives the outfit a recognizable shape.

Should the gray shirt go under or over the brown T-shirt?

Wear the brown T-shirt underneath the gray waffle thermal shirt. That layered look keeps the outfit warm and matches his layered screen outfit.

What kind of sunglasses make the look recognizable?

Use oversized black wraparound sunglasses with a shield-style shape. Regular small shades will not have the same wonderfully dramatic getaway look.

What trail shoes work for Bob’s look?

Black and orange trail shoes complete the look.

Should I add a rifle or another weapon?

The clothing works without a handheld prop. If you add the rifle seen in the film, use a nonfunctional costume prop with the right shape and check the venue’s rules. No rifle prop is included in this shopping list.

How to Dress Like Bob Ferguson (One Battle After Another)

Bob Ferguson, played by Leonardo DiCaprio in One Battle After Another, has one seriously memorable on-the-run look. He is not dressed like a polished action hero. He looks more like a guy who grabbed the nearest robe, glasses, and backpack before making a very fast exit. The red and black shadow-plaid robe, giant wraparound shades, and charcoal beanie do most of the comedy-heavy work. It is wonderfully scruffy, practical, and just strange enough to be instantly recognizable.

To build the outfit, layer the brown T-shirt under the gray waffle thermal shirt, then throw on the red plaid flannel robe. Add dark navy chinos, black socks, black and orange trail shoes, and the functional black backpack. Finish with oversized black wraparound glasses and the gray knit beanie. The red and navy robe has sharper tartan lines than the muted shadow plaid, while keeping the recognizable silhouette. Keep the bag useful and let the robe, beanie, and oversized shades define the look.

Bob Ferguson (One Battle After Another) Cosplay Ideas

Start with the base layers. Put on a plain brown T-shirt, then wear the gray long-sleeve waffle crew shirt over it. The thermal should be visible at the neck and sleeves, because Bob’s outfit is all about looking hastily assembled but oddly specific. Add dark navy chino pants for a simple, low-key bottom half.

Next comes the star of the show, the red and black plaid flannel bathrobe. A red and navy cotton flannel robe gives you the instantly funny silhouette, even though its tartan lines are more defined than the muted shadow plaid. Wear black socks from home and finish with black and orange trail shoes.

Pull the charcoal knit beanie low, then add oversized black wraparound sunglasses. They should look more like shield shades than ordinary fashion sunglasses. Sling on the black backpack, keeping it functional and free of unrelated tactical accessories. The shopping list focuses on his clothing and bag. An optional rifle-shaped costume prop should be nonfunctional and appropriate for the venue.

About Bob Ferguson (One Battle After Another)

Bob Ferguson is a character played by Leonardo DiCaprio in the 2025 film One Battle After Another. His screen outfit presents him in an on-the-run look built from ordinary clothing rather than a sleek hero uniform. His red and black shadow-plaid bathrobe, layered shirts, dark chinos, charcoal beanie, oversized wraparound glasses, trail shoes, and black backpack create a wonderfully odd mix of comfort, urgency, and accidental style.

People will recognize the costume because the robe and shield-like sunglasses make such a bold combination. It is funny without needing a giant logo or elaborate armor, which makes it a great choice for a casual convention or Halloween outfit. The screen robe has muted shadow plaid, while a red and navy flannel version offers a practical substitute with clearer tartan lines. The trail shoes are also a modern approximation, and the outfit works best when the backpack stays useful instead of turning into random tactical gear.
