Romulan uniforms were the clothing worn by officers in the service of the Romulan Star Empire, ranging from the 22nd through the 24th centuries. These uniforms facilitated the Romulan wearers' needs as scientists, warriors, and starship officers, often displaying rank insignia and position.
Distinguished by a formal collar, the jacket portion of the uniform was created from a checkerboard material, consisting of square-shaped patterning of various sizes and colors. A black tunic was worn beneath this jacket, also worn with black trousers and black, leather-like boots. Accenting the uniform was an elaborate belt or strap extending from the right shoulder, down to the left waist and across. (ENT: "Kir'Shara", "Babel One", "United", "The Aenar")
For this occupation, Remans were outfitted in close-fitting, rubber-like uniforms, distinguished by wide shoulder pads and high collars. Dark-purple or blue in color, these uniforms were ornamented by breastplates and hard ribbing on the upper-arms, probably intended for military or combat situations. (ENT: "United", "The Aenar")
Type A (mid-2260s)
For Romulans serving the Empire aboard starships in the 23rd century, uniforms consisted of a black undershirt, metallic-gold and black patterned tunic, and checkered, knee-length trousers, fastened by a wide black belt. The uniform trousers ranged in color from blue-black to red-black, with higher ranking officers in red.
These uniforms were worn with black boots, and often, black gloves. In addition, a Romulan disruptor was often worn with the uniform, fastened to the right side of the belt.
Higher ranking officers' uniforms were adorned with shoulder drapes, made from the same material as the trousers. Worn over the right shoulder, these drapes hung down to roughly knee-length, while remaining relatively short on the back, with a black, woolen fringe.
Some officers wore gold helmets adorned with gold triangles. These helmets completely covered the ears, chin and bridge of the nose, though this practice would fall into disuse by the next century. (TOS: "Balance of Terror", "The Enterprise Incident")
Female officers wore a high-collared, one-piece uniform variant that consisted of a shirt and miniskirt combination.
Made from the same golden-black patterned fabric as the male uniform version, the right portion of the uniform was made from the red or blue-colored fabric. The drape adornment was sewn directly onto the shirt and was worn under the belt, in contrast to the male uniforms. The drape was also shorter on the front, but was longer on the back than on male uniforms.
Type B (late 2260s and early 2270s)
A second type of Romulan duty uniform was observed in 2270. It consisted of a red long-sleeved shirt with white cuffs over which was worn a light blueish shirt with a scaled texture. Red pants and high boots of the same light blue color were worn underneath. The uniform was accessorized with a white sash tucked into a black belt belt with golden buckle. (TAS: "The Practical Joker")
During the 2290s, Romulan dignitaries and ambassadors, such as Nanclus who was present during the Khitomer Accords of 2293, wore clothing similar in style to those worn by the Romulan military of the next century.
Again making use of prominent patterning within the material of which it was made, the garments worn by Nanclus consisted of a blue coat, tan pants and boots, worn with a gold-colored sash that extended from the right shoulder to the left waist and across. The tunic bore a high collar and closed at the left chest. (Star Trek VI: The Undiscovered Country)
With the reappearance of the Romulans in the year 2364, new trends in their uniform style became evident.
Echoing the use of distinctly patterned material and large sashes in the previous century, 24th century Romulan military uniforms expanded on this look, enhancing it with a broad-shouldered tunic consisting of a silver-gray material. Worn with a black and red, similarly-patterned sash hung over the right shoulder and attached at the belt, this tunic featured a high collar (a silver-colored piece separate from the tunic) and wide sleeves that revealed black cuffs underneath.
Following their initial contact with the Federation in more than fifty years, subsequent encounters with the Romulans revealed yet another uniform design.
First observed in 2365, this second 24th-century Romulan uniform resembled the previous design, but discarded the drape or sash in favor of a harness-like belt structure, meeting at the chest from around both shoulders and extending down and around the waist. In addition, the collar was now sewn into and matched the tunic.
Although a more-generalized symbol has been observed, the crest of the Romulan Star Empire was displayed on the front of the belt and at the harness's V-connection on the chest, showing the familiar "bird of prey" clutching the twin planets Romulus and Remus. The majority of these uniforms featured similar, silver-gray material, but some Romulan officers wore uniforms of varying colors and patterns.
Although this style of uniform was phased out of common use as early as 2371, some Romulan officials (including General Velal) continued wearing it as late as 2375. (TNG: "Contagion", "The Enemy", "Face of the Enemy"; DS9: "Visionary", "The Dogs of War")
Tal Shiar variant
In keeping with the design prevalent in the 2360s, uniforms worn by members of the Romulan secret intelligence agency, the Tal Shiar, featured the same basic structure as the military's standard uniform.
Using far-less garish material than the standard uniform, this Tal Shiar variant came in a light-green color and was worn with gray trousers and boots.
As with the military uniform, a belt structure was worn, this time with an added strap on the right chest. As with future incarnations of the Romulan uniform, rank insignia – presumably unique to the Tal Shiar – was displayed on the left collar. (TNG: "Face of the Enemy")
By the early 2370s, the Romulan government once again phased into service a radically redesigned military uniform.
Abandoning the large shoulders and abbreviated sleeves, this more-generalized design came in only a dark-gray, thatched material for all ranks and positions observed. Featuring a black, mock-turtleneck collar, this uniform displayed rank on the left collar, and also featured a belt/harness structure - this time extending from the left shoulder, down to two straps running across the stomach. As before, the crest of the Romulan Empire was displayed, lower in this design than in the previous style.
Like their Starfleet counterparts, Romulans serving the Star Empire were sometimes required to wear formal uniforms for diplomatic affairs and state functions.
Consisting of a brownish-gray tunic and pants, the Romulan dress uniform was understated compared to the standard duty uniform, distinguished by black piping running down the chest, lining the seems at the shoulders and around the high collar. Like the standard uniform, the dress uniform displayed rank insignia on the left collar, with higher ranking officials wearing their rank on both sides. (DS9: "Inter Arma Enim Silent Leges")
Introduced as early as 2379, a fourth version of the Romulan military uniform was observed, this time a striking departure from, or return to, earlier designs, while retaining the same Romulan style.
Distinguished by its use of a distinctive and colorful checkerboard jacket, this uniform was worn with a formal black under tunic, black trousers and heavy, black boots. Again featuring a harness-like belt structure worn over the jacket, this uniform design bore a far less elaborate belt, marked by several metal rings and flourishes and extending from the right chest, down to the left waist and across. Also like earlier designs, this Romulan uniform sported a Romulan crest, somewhat redesigned and worn at the center of the neck on the collar. (Star Trek Nemesis)
Senate guard uniform
Consisting of a long, heavy tunic, dark-brown, blue and green in color, this uniform featured a high collar and large shoulders. The sleeves of the tunic were bulky and ended in heavy gloves decorated with metal rings and flourishes. This uniform was worn with large, heavy boots, similarly accented with metallic embellishments and built with thick soles. (Star Trek Nemesis)
Resembling (if not identical to) their 22nd century counterparts, the uniforms worn by Reman soldiers in the service of the Romulan Star Empire were radically different from those worn by the Reman's Romulan overlords.
The standard duty uniform worn by those Remans serving aboard starships – including the renegade Shinzon's vessel, the Scimitar – consisted of a tight-fitting, rubber-like jumpsuit. Dark-purple in color, these uniforms possessed a colorful, iridescent sheen.
Adorned with gold piping and dark, metallic-purple accents, the Reman duty uniform featured a high collar and broad, up-swept shoulders. The uniform was also heavily armored, ribbed on the sleeves, sides and legs. (Star Trek Nemesis)
A variant of the Reman duty uniform, an even more heavily armored version existed.
Worn by lower-ranking Remans taking part in battle or tactical situations, this uniform featured a heavy breastplate structure not present in the standard duty uniform. Also present on the uniform, was a holster for easy access to the wearer's sidearm. Retaining the same structure, style and coloration of the standard uniform, this combat-style uniform was also supplemented by a more elaborate counterpart.
Worn by senior ranking Reman officers, the more intricately decorated combat uniform featured a highly detailed vest, with heavy shapes on the chest and back, and a long, cape-like coat.
Far less ostentatious than other observed Reman uniforms, Reman medical doctors and surgeons wore white, plastic-like operating scrubs and purple gloves and masks. Consisting of long, medical smocks and pants, these scrubs were distinguished only by several dark lines running vertically down the chest and sleeves.
