A Beginner’s Guide to Building a Knight Templar Costume

Building your first Knight Templar costume can feel overwhelming — there are tunics, mantles, mail, crosses and a dozen accessories to weigh up, and plenty of ways to get the details wrong. The good news: you do not need everything at once, and a convincing look comes down to a few core pieces layered in the right order. This beginner’s guide walks you through the essential layers, shows you how to get the all-important red cross right, and helps you decide where to spend and where to save — whether you are dressing for a party, a fair, or your first steps into serious reenactment.

Start with the silhouette, not the shopping list

Before buying anything, picture the finished look, because the silhouette is what makes a costume instantly “read” as Templar. The classic image is a figure in a long white mantle or surcoat bearing a red cross, worn over a plain tunic, belted at the waist, with the suggestion of armour beneath. Get that outline right and the eye fills in the rest.

That means your first decisions are about layers and proportions, not gadgets. A costume that flows and drapes correctly will always look better than one weighed down with cheap plastic accessories. Think in terms of a base layer, a mid layer, and the cross-bearing outer garment.

The core pieces every beginner needs

If you buy nothing else, get these four:

• A plain tunic. A simple, long-sleeved undertunic — usually off-white, cream or a muted colour — forms your base layer.
• A surcoat or tabard. This is the sleeveless overgarment that carries the cross. For a knight it is white, and it goes over everything else.
• The white mantle (cloak). The flowing cloak is the most iconic Templar garment and does the most work in creating the silhouette.
• A sturdy belt. A leather belt cinches the look and gives you somewhere to hang a scabbard or pouch.

Fit and length matter more than most beginners expect. Medieval garments generally sat loose and long — a tunic to mid-thigh or knee, a mantle that falls well down the back — so resist the urge to size everything tight and modern. Natural fibres such as wool and linen drape and photograph far better than shiny synthetics, and they read instantly as “period” even from across a room.

For fabrics and cuts that lift a costume toward genuine reenactment quality, our guides to recreating historically accurate attire and to choosing the right cloak and tunic materials are the natural next step once the basics are in hand.

Getting the cross right

Nothing marks a Templar costume — or gives away a lazy one — like the cross. A few rules keep you accurate:

• Colour and placement. The Templar badge is a red cross on white, granted by Pope Eugenius III around 1147. It typically sits on the left breast of the mantle and larger on the surcoat.
• Knight vs sergeant. A professed knight wore white; the order’s sergeants and serving brothers wore black or brown — but always with the same red cross. Choosing black instantly reads as a sergeant, which can be a smart, distinctive option.
• Cross shape. The iconic form is the cross pattée, whose arms flare toward the ends. A plain straight cross reads more generically crusader than specifically Templar.

How you apply the cross also affects the finish. A sewn-on felt or fabric cross looks far more convincing than a printed or iron-on transfer, which can shine or peel under lights. If you sew, cut the cross cleanly and symmetrically — a slightly wonky pattée is the detail people notice first. Get the colour, placement and shape right, and even a modest costume looks deliberate rather than thrown together.

Armour and accessories: where to spend, where to save

Beyond the cloth, accessories add realism — but this is where budgets balloon, so choose by tier:

1. Head. A simple mail coif or arming cap suggests a knight ready for battle; a full helm is a bigger investment for later on.
2. Body armour. Real riveted mail (a hauberk) is heavy and costly. Beginners can use lightweight faux mail or simply let the surcoat imply the armour beneath.
3. Padding. A gambeson (padded jacket) is the layer worn under mail; even on its own it adds convincing bulk.
4. Sword and shield. A cross-hilted sword and a white shield with a red cross complete the picture. For display a wall-hanger is fine; for reenactment buy blunt, event-legal steel.
5. Footwear. Plain leather boots or turnshoes beat modern trainers every time.

Spend first on the pieces people see most — mantle, surcoat and cross — and add armour gradually. If you want a made-to-measure over-layer, our pattern and fit guide for a custom Templar tabard shows how to tailor one properly.

Keep practicality in mind, especially for a first outing. Real mail is heavy, and a full kit worn all day in summer heat is genuinely tiring — the historical Templars felt this keenly in the Levant. If you are attending an organised event, check its safety rules in advance: many require blunted blades, peace-tied scabbards or specific armour standards. Comfort and compliance will do more for your day than one extra shiny buckle.

Common beginner mistakes to avoid

A few easy fixes separate a costume that works from one that does not:

• Wrong cross shape or colour — a pinkish or oddly proportioned cross undercuts everything else.
• Shiny, obviously plastic “armour” that catches the light unnaturally.
• Modern giveaways — visible zips, elastic, trainers, or a wristwatch.
• Mixing up the garments — treating the monastic mantle and the battlefield surcoat as if they were the same thing.

None of these require money to fix; they simply require knowing what to look for. A useful habit is to photograph yourself in the finished kit and study it critically, the way you would a stranger’s costume — the camera is honest about the anachronisms your eye has stopped noticing. Fix the two or three that jump out, and your overall impression climbs sharply without a single extra purchase.

The easiest way to start

If a full kit is more than you want to take on right now, you can still carry the Templar look with almost no effort. Our TEMPLAR SHIELD — TEMPLAR SHIRTS design puts the shield-and-cross motif on an everyday shirt — a painless first step that pairs well with a cloak for a quick costume or stands on its own day to day.

Think of your first build as a foundation rather than a finished project. Almost everyone refines their kit over time — swapping a synthetic for wool here, upgrading a printed cross to a sewn one there, adding a coif or a better belt as funds allow. The pieces you choose well at the start will still serve you two or three iterations down the line.

Building a Templar costume is a journey best taken one layer at a time: nail the silhouette, get the cross right, and add armour as your interest (and budget) grows. Start simple, stay accurate where it counts, and you will look the part long before you own every last buckle.
