Some things I did for my Dragon Age modern AU --

The uniform of a Templar Knight-Captain. This is what Ser Cullen wears on a day-to-day basis. The left version is normal service dress (No. 2) -- note the dirk and sidearm -- and the right version (No. 6) is worn for ceremonial guard postings, such as at the entrance to a Circle or at the Chantry. The belt buckle bears a quotation from Benedictions 4:10. The uniform does not include an official headdress, but most Knight-Commanders prescribe a black beret or peaked cap with the service uniform and an open helmet with the guard uniform.
The inspiration from British military uniforms of the late 19th century should be fairly obvious. In addition, I also tried to keep in mind the symbols of the Order we see in the games.
Other uniform variants are No. 1: full plate armour over clerical vestments, for ceremonial purposes only, No. 3: a tropical version of No. 2 service dress, with a white tunic, which is standard dress in Rivain and Antiva, No. 4: dress uniform, which adds a scarlet, golden or violet sash for officers, a black cape and full orders, No. 5: high guard uniform, like No. 6, but with additional plate armour and a full helmet, No. 7: light combat uniform, for anti-magic policing actions (think SWAT teams), No. 8: full combat uniform, for full-scale war, No. 9: plain white vestments for a recruit's vigil, No. 10: undress uniform, consisting of a white shirt, black trousers, a black tie and a dark red pullover, No. 11: like No. 10, but without the pullover, Nos. 12, 13, 14 and 15: special variants for use at the Grand Cathedral, the Knights-Divine in the presence of the Divine, for the investiture or funeral of a serving Knight-Commander or Grand Cleric, and replacing No. 2 and its variants during an Exalted March when not serving at the front.

Quick sketch of Grey Warden uniforms, in the same Modern AU as my oneshot Born Free and Everywhere in Chains. Stolen from the wardrobes of Warden-Commander HM Queen Eleanor Cousland SWV, Senior-Warden-on-permanent-leave HM King Alistair of Ferelden, Warden Nathaniel Howe and Warden Velanna of Clan <unknown>.
Note the collar patches -- all Wardens, upon their joining, are assigned to one of three orders, those of the Warriors (sky blue), Rogues (black) and Mages (red). In the Dragon Age, the former two terms have become hugely anachronistic, but some rough equivalence to modern combat roles still persists. A recruit who is trained or has been trained in heavy combat armour, stormtrooping tactics and melee combat will generally be assigned to the Warriors, with the vast majority of other recruits going to the Rogues, where they serve in roles ranging from snipers and artillerymen over combat engineers and medics to cooks and archivists. Any organisation the size of the Wardens also has a significant support body attached; though most non-combat support roles are taken over by non-Wardens -- more precisely, "lay" members of the order who have not taken the Joining --, a significant number of Wardens serve in non-combat roles. Either made invalid by some injury or age or recruited for specialist skills, these non-combatants are still Wardens, and every Warden is trained at arms.
Service Dress is nearly identical for all ranks and orders, distinguished only by the collar patches and epaulettes. Lady Wardens may elect to substitute a navy skirt for the usual black trousers, as Warden-Commander Cousland has done here. A particularity of Warden uniforms is that only distinctions awarded by the Order may be worn, of which there are not many. Commander Cousland's uniform displays the badge of the Silverite Wings of Valour, awarded for her role in the Fifth Blight. Though she holds a large amount of other honours awarded by various nations of Southern Thedas, including the Royal Order of the Mabari and the Grand Star with Diamonds of the Fifth Blight, she is not permitted to wear them with her Warden uniform.
Senior-Warden-on-permanent-leave HM The King displays Warden-issue heavy armour. Though surface armies have long abandoned armour and plate, the tactics employed by the Darkspawn still necessitate some kind of body protection. Based on an inner layer of padded fabric armour with chainmail-inlay, non-flexible areas are further reinforced with steel plating. Trials with lighter ceramic plating, standard in surface armies and for firearm protection, proved unable to resist the melee weapons employed by the Darkspawn horde. An onboard computer system monitors the Warden's lifesigns, and important combat data is projected on a HUD inside the helmet. The heavy armour is highly versatile and compatible with Warden issue shields and a variety of light and heavy weaponry ranging from swords to flamethrowers. Their weight, however, significantly encumbers the wearer and requires special training to wear in combat. In addition, all these feature, make heavy armour prohibitively expensive. Since its introduction in 9:28, fewer than 1000 full suits have been issued, and 93 were lost at the Battle of Ostagar. In future, these armours may become cheaper to mass-produce, but until then, suits are passed down from warrior to warrior.
Significantly lighter and cheaper than the heavy armour is what has been called "medium armour". Worn by the majority of Warden combatants, this suit of padded fabric armour with chainmail inlay offers basic protection against piercing weapons, light firearms and elemental magic. The left arm is more heavily armoured and can be used to shield the wearer from blasts or hazardous liquids. The onboard computer functions as a PDA to assist the Warden in their duties, and the heavy-duty utility belt provides storage room for a variety of tools. Depending on the Warden's role, a wide variety of customisations can be made: for example, long-range specialist Howe employs a programme that provides targeting aid under Deep Roads conditions.
The most basic armour used by Wardens is that worn by the order's mages. The complicated gestures required for many magics make heavier armour unviable for the vast majority of mages, though some have been known to use their magic to assist in wearing even heavy armour. Mage armour consists of the same padded fabric as forms the basic layers of medium and heavy armour, but without the chainmail inlay or any additional protection. Designed to be easy to wear and move in, mage armour offers scarcely more protection than normal clothes and requires that mage Wardens operate with the protection of more heavily-armoured comrades.
Heavy armour obviously inspired by Mass Effect's N7 armour, medium armour by SWTOR's Imperial Agent Kell Dragon / Shadowed armours.
