only headdress worn without a cap badge or other distinction). On 'informal parades' officers in Nos 2 or 6 dress may wear a peaked khaki cap (which may also be worn with Nos 4, 7, 12, 13 and 14 dress); this item is not generally issued to other ranks (who would wear the beret or equivalent on these occasions) except those in HCMR and King's Troop RHA. Another item of headwear authorized (but not provided) for optional wear on informal parades in Nos 2 or 6 dress is the side cap; it may also optionally be worn with Nos 4, 6, 7, 10, 11, 13 and 14 dress. No.3: Warm weather ceremonial uniform No.3 dress is the warm weather equivalent of No.1 dress, worn for specified overseas stations or assignments. With the introduction of No.1 Dress in temperate regions, No. 3 Dress was adopted as the tropical equivalent during the early 1950s. It comprised an all-white cotton drill high-collared tunic, cut in a similar fashion to the No. 1 dress jacket, plus white trousers. These were worn with the coloured No.1 dress cap.

Since the 1970s this order has consisted of the same white tunic but is now worn with coloured No. 1 dress trousers. Head-dress, footwear and badges are generally as for No. 1 dress. Widely worn during the 1950s and 1960s (when Britain still maintained significant garrisons in tropical stations) this uniform is now usually restricted to military attachés in tropical postings and their personal staffs; units of the Royal Gibraltar Regiment and The Royal Bermuda Regiment (see below); plus a few army bands and officers of the battalion of the Royal Gurkha Rifles stationed in Brunei. The band of the Royal Gibraltar Regiment is entitled to a permanent issue of No. 3 dress. The Royal Bermuda Regiment, which has many ceremonial duties, issued No. 3 Dress as a summer uniform until the end of the millennium, wearing No. 1 Dress (with red facings) during the rest of the year due to the cold and often stormy weather.
