// AR 670-1 — WEAR AND APPEARANCE OF ARMY UNIFORMS AND INSIGNIA
Major update in progress: A September 2025 Army directive substantially rewrote the appearance and grooming chapter — replacing photo examples with exact measurements to remove ambiguity. Soldiers were given 30 days from that directive to meet the new standards, and implementation guidance (Army Directives 2025-13 and 2025-18) is still working through the force. Treat every measurement below as a general reference point, not a substitute for the current AR 670-1, DA PAM 670-1, and your unit's current guidance.

Purpose & Philosophy Chap 1

"The Army is a profession. A Soldier's appearance measures part of their professionalism." AR 670-1 exists to keep every Soldier's appearance uniform, disciplined, and professional — on duty, and in civilian clothes while on duty.

Who It Applies To

  • All Soldiers — Regular Army, Army National Guard, and U.S. Army Reserve
  • ROTC and U.S. Military Academy cadets, unless their own uniform regulations say otherwise
  • Retirees, whenever they wear an Army uniform (see Special Situations)

Commander Responsibilities

Commanders ensure compliance with this regulation and DA PAM 670-1 within their unit, and conduct periodic inspections to verify Soldiers meet uniform and grooming standards. Soldiers are responsible for maintaining their own uniform items and ensuring their appearance conforms to the regulation at all times.

Punitive Provisions Enforceable

Most of the appearance and grooming chapter is punitive. Violations by Soldiers can result in adverse administrative action and/or charges under the Uniform Code of Military Justice — this isn't just a style guide.

Local Policy Can Be Stricter

Unit and command policies may be more restrictive than AR 670-1 itself. Always confirm with your chain of command on any point where local policy might layer additional requirements on top of the regulation.

Male Hair Updated 2025

Hair on top must be neatly groomed, tapered, and conservative — the outline should curve inward to a natural termination point at the base of the neck. Hair cannot fall over the ears, eyebrows, or touch the collar (except closely-cut hair at the back of the neck). Under the current standard, bulk at the top tops out around 2 inches, with stricter fade/taper requirements than the prior version.
  • Braids, cornrows, twists, dreadlocks, and locks are not authorized for men in uniform or in civilian clothes on duty
  • Designs, asymmetrical cuts, and eccentric styles (e.g., a single untapered patch on top) are prohibited
  • Hair color must look natural — no extreme contrasts
  • Shaved heads are authorized

Female Hair Updated 2025

Hair must be styled so headgear fits properly and presents a neat, professional appearance. Braids, cornrows, twists, and locks are authorized, worn loose or close to the scalp, each of uniform dimension and consistent spacing, with ends secured inconspicuously.
  • Ponytails and braids are authorized with utility/physical-fitness uniforms but generally prohibited with dress uniforms
  • Where authorized, ponytails/braids are limited in width and how far they hang below the collar — check current exact figures locally
  • Hair extensions and wigs are authorized if they match the general appearance of the Soldier's natural hair
  • Shaved heads are authorized

Facial Hair Updated 2025

Beards are prohibited except with an approved medical shaving profile or an approved religious accommodation. Mustaches must stay above the upper lip and not extend past the corners of the mouth, trimmed and tapered — no "bushy" or "chopped off" look.
  • Medical shaving profiles now follow a phased treatment plan (roughly 30/60/90-day tiers depending on severity), with elective treatment options at government expense for non-responsive cases
  • Accumulating more than about 12 months of shaving exceptions within a 24-month window can be grounds for administrative separation review
  • Approved religious-accommodation beards must be kept trimmed/rolled to a regulation length — verify the current exact limit with your chain of command

Fingernails & Nail Polish Updated 2025

Nails may not extend past the fingertip for men, and up to about a quarter inch for women, in a square or rounded shape.
  • Women: only clear nail polish is authorized
  • Men: nail polish is not authorized

Tattoos & Body Art

Content restrictions apply everywhere on the body, regardless of location: tattoos that are extremist, indecent, sexist, or racist are always prohibited and can lead to adverse administrative action.
  • Army tattoo policy has loosened considerably over the past decade — commanders conduct periodic checks focused on placement above the neckline, on wrists, and on hands
  • Willful mutilation of the body (e.g., tongue bifurcation, ear gauging beyond a small conservative post hole) is prohibited
  • Exact size/placement limits have changed multiple times — verify current guidance rather than relying on older figures

Jewelry & Eyewear

Eyeglasses must be conservative — no trendy designs, initials, or decorative elements.
  • Sunglasses are not worn indoors unless required by a medical authority; authorized lens colors are limited to brown, gray, or dark green
  • No decorative chains or ribbons on eyewear, except restraints required for safety
  • Contact lenses cannot be tinted to change eye color/shape except for a documented medical condition
  • Earring and jewelry authorizations vary by uniform (utility vs. dress vs. PT) — check DA PAM 670-1 for the specific uniform you're wearing

Army Combat Uniform (ACU / OCP)

Consists of the coat and trousers in the Operational Camouflage Pattern, worn with specific undergarments.
  • A Tan 499 undershirt is worn tucked into the trousers
  • A Tan 499 rigger belt secures the waist
  • A cold-weather, silk-weight, moisture-wicking undershirt may substitute for the standard undershirt when conditions call for it

Army Green Service Uniform (AGSU) & Dress Uniforms

The Army Green Service Uniform replaced the blue Army Service Uniform as the day-to-day service uniform (chapters 14–15 cover design and wear in detail).
  • Lapels and sleeves of service, dress, and mess coats/jackets are roll-pressed without creasing; skirts are not creased
  • Trousers, slacks, and shirt/blouse sleeves are creased
  • Starch, sizing, dry-cleaning, or steam-pressing wash-and-wear items is not authorized — it degrades the fabric treatment

Army Physical Fitness Uniform (APFU)

The standard PT uniform, worn for physical training and authorized off-installation activities per local policy.
  • Breastfeeding/pumping Soldiers may wear an optional T-shirt designed for that purpose and may unzip or remove the ACU coat or other uniform jacket while actively breastfeeding
  • Religious accommodations can include a long-sleeved APFU top and subdued (non-patterned) leggings worn under APFU shorts

Insignia Placement — General Principles

Rank insignia is centered on the shoulder loops; unit (shoulder sleeve) insignia is typically worn on the right sleeve. Soldiers wear only insignia and awards authorized by this regulation, and only uniform/heraldic items produced by certified manufacturers that meet Army specifications.

Identification Tags

Soldiers wear identification tags at all times while on duty in uniform, unless otherwise directed by the commander.

Footwear

Boots must be cleaned and polished to maintain a professional appearance — footwear condition is one of the more visible, easiest-to-check compliance items during an inspection.

Uniform Quality Control

Anyone purchasing uniform or insignia items from a commercial source must ensure those items meet the same specification requirements as issued items. Commanders submit quality deficiency reports for items that don't meet standard.

Retirees Wearing the Uniform

AR 670-1 applies to retirees any time they wear an Army uniform.
  • Authorized occasions include ceremonial events — funerals, memorial services, weddings, and similar occasions
  • Ceremonial wear is restricted to service and dress uniforms only
  • The APFU may be worn only in combination with civilian clothes, off Army installations
  • Retirees may add approved retired shoulder-sleeve insignia and identification badges

Civilian Clothes on Duty

Hair, fingernail, and grooming standards apply in civilian clothes on duty exactly as they do in uniform. Mixing civilian and military clothing items together is prohibited unless this regulation specifically authorizes it.

Religious Accommodations

Soldiers may request religious accommodation for items such as beards, turbans, and hijabs. Requests are submitted under AR 600-20 (Army Command Policy); once approved, Soldiers follow the specific wear standards for that accommodation set out in AR 670-1 and current implementing guidance.
  • Hair worn under an approved turban does not have to meet standard haircut rules, but it still cannot touch the ears/collar or fall below the eyebrows
No reference cards match that search.
