Ash Costume Essentials

How To Dress Like Ash

How To Dress Like Ash From Rainbow Six

Ash's look is all about practicality and tactical readiness. Here's a deeper dive into nailing her signature style:


  • What You Need:
    • Black long-sleeved shirt or thermal undershirt
    • Black cargo pants (with multiple pockets)
    • Black combat boots
  • How To Do It:
    • Start with a form-fitting black long-sleeved shirt. This creates a sleek silhouette and mimics the look of Ash's tactical gear. A thermal or compression shirt adds an extra layer of ruggedness.
    • Find a pair of durable black cargo pants. The more pockets, the better! These will not only look the part but also give you places to stash accessories and mimic Ash's prepared nature.
    • Complete the base look with a pair of sturdy combat boots. Opt for a style with a bit of a heel to add to Ash's powerful stance.
  • Bonus Tip: Don't worry if you can't find the perfect items in your closet. Thrift stores and army surplus shops are great places to score affordable tactical-looking clothing at a fraction of the cost.

Tactical Gear

  • What You Need:
    • Black tactical vest
    • Black drop leg holster
    • Black tactical leg pouch
    • Knee pads
  • How To Do It:
    • The tactical vest is Ash's most recognizable wardrobe piece. Search online retailers or military surplus stores for a vest with plenty of pockets and MOLLE webbing for attaching accessories.
    • Add a black drop leg holster to showcase your toy weapon and give yourself a quick-draw advantage.
    • Include a tactical pouch on your opposite leg – Ash is always prepared! This is a great place to stash your phone or other small essentials.
    • A set of black knee pads completes the ready-for-anything aesthetic. Opt for a style with hard plastic caps for a more realistic look.
  • Bonus Tip: If you're feeling ambitious, try weathering your tactical gear slightly. A light dusting of gray spray paint can give the impression of wear and tear from missions.


  • What You Need:
    • FBI baseball cap
    • Aviator sunglasses
    • Fingerless gloves (preferably gray and black)
    • American flag patch
  • How To Do It:
    • A simple black FBI baseball cap instantly brands you as part of Rainbow Six. Look for a subtle design without excessive logos
    • Aviator sunglasses give Ash an air of unflappable confidence. Stick with the classic silver frame and dark lenses.
    • Find a pair of two-tone fingerless gloves, ideally with gray palms and black fingers. This adds interest and mimics the real-life tactical gloves used by operators.
    • Securely attach an American flag patch to your vest or sleeve. This small detail shows Ash's national pride and commitment.
  • Bonus Tip: If you're worried about losing your sunglasses in the Halloween chaos, consider a cheap pair you won't mind if they get misplaced.

Signature Weapon

  • What You Need:
    • Toy AK (or other assault rifle-style toy)
  • How To Do It:
    • While replicating Ash's M120 CREM launcher is tricky, any toy assault rifle conveys her role as a breacher. Opt for a larger model for greater impact.
    • If you want increased accuracy, add realistic details to your toy weapon. Use black, gray, and silver paint to mimic buttons, dials, and the look of real metal.
  • Bonus Tip: Look for toy weapons with removable magazines or straps for added realism and a place to attach it to your vest when not in use.

Finishing Touches

  • What You Need:
    • Optional: smudge-proof black eyeliner
    • Optional: temporary black hair dye spray
  • How To Do It:
    • Take your Ash costume to the next level with "battle-worn" makeup. Use a smudge-proof eyeliner to create subtle streaks around your eyes and cheekbones, suggesting combat intensity.
    • If your hair is significantly lighter than Ash's, consider a temporary black hair dye spray. This adds to your transformation and makes you even more recognizable.

Ash Cosplay

Ash isn't just about her gear; she exudes strength and determination. Here's how to channel her focused energy:

How to Act Like Ash at the Halloween Party:

Confidence is Key

  • What to Do: Project an air of self-assurance How to Do It:
    • Stand tall with good posture. Keep your chin up and shoulders back – you own the room!
    • Make eye contact. Ash isn't one to shy away from a challenge or conversation.
    • Speak clearly and with purpose. Your words carry weight.
  • Bonus Tip: Even if you don't feel entirely confident, faking it can go a long way. Your Ash costume provides half the battle armor!

Focused Intensity

  • What to Do: Show your mission-driven mindset How to Do It:
    • When engaged in conversations, stay on topic. Ash isn't easily distracted.
    • Be decisive. Don't waffle or offer too many options – you're here to get the job done.
    • Use direct language. No need for flowery phrases, get to the point quickly.
  • Bonus Tip: If people are trying to pull you into silly party antics, deflect with a line like, "Got an objective to complete. Catch you later."

Quiet Leadership

  •  What to Do: Command respect without being overbearing How to Do It:
    • Don't feel the need to be the loudest person in the room. Your presence is powerful enough.
    • Provide assistance if you see someone struggling. Ash leaves no teammate behind.
    • Offer solutions confidently, not criticisms. A leader solves problems.
  • Bonus Tip: Team up with a friend dressed as a fellow Rainbow Six operator! You can play off each other's energy and create a dynamic duo.

A Hint of Humor

  • What to Do: Show a subtle sense of dry wit How to Do It:
    • If someone compliments your costume, respond pragmatically. "It's functional" is more Ash than "Thanks, I love it!"
    • Use sarcasm sparingly but effectively. A well-timed eye roll can convey volumes.
    • Be more amused than outwardly laughy. A smirk is more Ash's style.
  • Bonus Tip: Study some of Ash's in-game dialogue to get a feel for her understated humor and word choice.

Remember, Ash is a complex individual. Take these cues and add your own spin to make the character your own!

Couple, Group, & Family Costume Ideas

Channel the tactical prowess of Rainbow Six Siege with these creative costume combinations inspired by Ash and her operator colleagues.

Couple Costume Ideas

  • Ash and Jäger: A clash of tactics! Ash's headstrong breaching style contrasts nicely with Jäger's defensive focus and gadget prowess.

  • Ash and Bandit: Play up the backstory tension. Ash and Bandit (formerly teammates) have a touch of friendly rivalry, which can be fun for a couple's costume.
  • Ash and Kali: Embrace the rivalry! This is a great option for a couple who enjoys some playful competition. Ash's headstrong style contrasts perfectly with Kali's more calculated approach.

  • Ash and Blackbeard (or other GIGN Operator): Showcase Rainbow Six Siege's international task force. Pair Ash with fellow operator Blackbeard, or choose another GIGN member like Montagne or Twitch.

Group Costume Ideas

  • Original Rainbow Six Siege Squad: Gather your friends and assemble the classic operators. Include Ash, Thermite, Pulse, Castle, and Twitch for the starting line-up from the game.

  • FBI SWAT Team: If you've got a larger group, go all-in on Ash's FBI roots. Multiple Ashes, Castle, Thermite, and Pulse make for a visually striking crew.

  • Battle of Tech: Pit Ash and her tactical gear against the technologically advanced operators. Ash, Echo, IQ, and Dokkaebi would make an intriguing mix of old-school vs. new-school techniques.

Family Costume Ideas

  • Family of Operators: A truly dedicated family could dress as an entire Rainbow Six Siege team! Assign roles based on personality – Ash is the bold leader, while someone like Doc is the team medic.

  • Rainbow Six Goes Undercover: Take a humorous approach! Ditch the tactical gear and dress your family as "undercover" versions of the operators. Sunglasses and trench coats over regular clothes could signal their secret identities.
