The Service Dress Blue is the standard uniform of the day for office environments and is considered equivalent to civilian
business attire. The uniform consists of a blue four-pocket single breasted jacket, matching trousers, and a tie of the same shade as the jacket. There are two variants. The less common but more formal "Alpha" variant includes a white shirt and a
combination cap (or "combo cover" in common Coast Guard slang) is always worn with it. The more common "Bravo" variant includes a light blue shirt and is worn with either the combination cap or a blue
garrison cap matching the coat.
Officer and
enlisted rank insignia are sewn onto the jacket sleeve in the same manner as Navy uniforms. Rank insignia must also be worn on the blue shirt as part of the "Bravo" variant by officers (shoulder boards) and enlisted members (collar devices). The Service Dress White "choker" uniforms for officers are identical to those worn by U.S. Navy officers (aside from service-specific buttons, insignia, and sword design). These are typically used for formal parades and
change-of-command ceremonies in warmer seasons and climates. Unlike the Navy, these uniforms are authorized only for officers and warrant officers, not chief petty officers. For similar occasions the enlisted members wear Tropical Blue, Service Dress Blue, or Full Dress Blue, depending on the climate. Uniform regulations already allowed that, where Service Dress Blue Bravo is the standard uniform of the day in office environments, the coat could be removed during the work day. Both the short and long-sleeved light blue shirts are the same style and color as used by the U.S. Air Force. wearing the Winter Dress Blue uniform with
garrison cap The Winter Dress Blue uniform is an optional variant of the Service Dress Blue Bravo. This uniform was originally only authorized during winter months from 1 November to 31 March, but has since been authorized to be worn year round in situations where the formality of the Bravo jacket is not required. It consists of a long-sleeve dark blue shirt of the same color as the service dress trousers, without shoulder loops. It is worn with the blue necktie and rank insignia pins on the collar (unless a sweater is also worn, in which case the rank is worn on the sweater instead). All blue service and dress uniforms are worn with a black, plain-toe
oxford shoes or, optionally, black
pumps or flats for females.
Patent leather versions are authorized. White shoes are worn with the dress white uniforms. Several optional forms of outerwear may be worn with some or all of these uniforms, all in dark blue, including: a windbreaker; a "wooly pully" commando-style sweater; a
cardigan sweater (the same worn by the U.S. Air Force); a
trench coat; a waterproof
parka; and, for officers, a double-breasted
bridge coat (similar to a
pea coat but knee-length). == Dress uniforms ==
