The peaked cap — stiff crown, shiny leather peak, badge front and centre — is one of the most recognisable pieces of formal military headwear there is, and it looks essentially the same whether it's Army, RAF or Royal Navy. That's not laziness on the designers' part; the shape does real jobs.

Why the stiff, structured shape
Unlike a beret, a peaked cap holds a fixed, upright shape regardless of how it's worn — which matters enormously for ceremonial and formal dress, where a uniform, sharp silhouette across an entire parade is the whole point. The stiffened crown and wire-supported peak keep every cap on every head looking essentially identical, which is exactly what a formal inspection line needs.
The peak itself is functional, not just stylish
The leather or patent peak does the same basic job any cap peak does — shading the eyes — but on formal dress it doubles as a visual anchor for the cap badge, which sits directly above it at the front, making the badge instantly visible from a distance in a way a beret badge (worn to the side) isn't. Senior officers' peaked caps also traditionally carry "scrambled egg" — gold oak-leaf embroidery on the peak itself — above a certain rank, a genuine visual rank marker in its own right, separate from any insignia worn on the shoulder or sleeve.
Why it looks similar across services
The Army, RAF and Royal Navy all use variations on the same basic peaked-cap silhouette for formal dress — differences come down to colour, badge, and cap band detail rather than the fundamental shape, because the shape itself is solving the same problem (structure, visibility, uniformity) regardless of which service is wearing it. See our RAF/RN/RM uniform guide for how each service's version differs in colour and detail.
The cap band and badge do the identifying work
Because the basic shape is so consistent, the actual identifying details sit in the band around the base of the crown and the badge itself — different regiments and corps use different band colours and patterns, in the same way lanyard and stable belt colours identify a unit elsewhere on the uniform. It's worth checking the band colour matches the badge and the regiment you're after, rather than assuming any peaked cap will do with the right badge simply pinned on.
What to check when buying
Genuine peaked caps are sized around the head circumference in centimetres, same principle as our general sizing guide covers for headwear — measure carefully, since a badly-fitted peaked cap is one of the more obvious things to get wrong in a formal dress impression. It's also worth checking the peak material (patent leather vs a matte leather or synthetic finish) matches what's correct for the specific service and era you're after, since this has changed over time.

Checking one before you buy
Peaked caps are among the easiest items to buy badly, because the failure modes are hidden until it arrives:
- The wire frame — the crown is held out by a stiffener. If that has collapsed or been removed, the cap will never sit right again and cannot really be repaired.
- The sweatband — leather, and the first thing to perish. Check for cracking and for the size stamp, which is often the only sizing information on the cap.
- The badge hole — if a badge has been removed, look for a stretched or torn hole in the band. That devalues an otherwise good cap.
- Peak condition — the patent finish on a dress cap peak crazes with age and cannot be restored.
Sizing is not the same as a modern hat
Military caps are sized to the head in inches or centimetres rather than S/M/L, and they are meant to be a firm fit — a cap that can be pushed around on the head is too big and will look wrong immediately. If you are buying without trying, measure around the head just above the ears and buy to that, not to your usual cap size.
