The US Army Air Corps Mess Dress summer uniforms looked like white jackets and black trousers. At least this was the case until the early part of the 1980s.
The US Army is presently going to dress blues.
Their band is part of their ROTC Corps of Cadets.
The dress uniforms are loosely based on Soviet Uniforms, while the current fatigue uniforms are the Type 07 digital pattern uniforms.
Per ALARACT 203/2010, the CSIB is now authorized as optional wear for the Army Blue Mess and Army White Mess dress uniforms.
Under the Laws of War, soldiers dress in uniform. The uniforms can be anything--you could dress your army in blue jeans and work shirts, like the Navy did--but they have to be recognizable as the uniform of that army.
Yes, but not every ribbon is approved for wear on Army uniforms, IIRC.
The combat uniforms are the same yes, the only difference being is rank insignia. However dress uniforms are varied by rank
The United States Army Band (Pershing's Own) wears Civil War-style rank on its dress uniforms. The uniform itself is designed after 19th-century Army uniforms.
I am guessing around 1900 http://members.tripod.com/~Fbg_mem_museum/uniftalk/unipat2.htm
You get several different types of uniforms - PT uniform, dress uniform, ACU uniform, etc.
This may be an unpopular answer for some people, but the number ONE most world-wide recognized uniform is the U.S. Navy enlisted Dress Whites and Dress Blues ("crackerjacks"). Much of the reasoning is the U.S. Navy presence throughout the world, that is an advantage over other countries and other U.S. branches of military. The Marine Corps dress blues are most likely in your "top 5" HOWEVER...to the untrained eye, many civilians confuse Marine Corps and Army service and dress uniforms as they are (again, to the untrained eye) similar in appearance. Marine and Army service uniforms both include green slacks/trousers. Marine and Army dress blues both have blue trousers with single stripes down each side WITH a black jacket with trim around the edges. Conversely, with the U.S. Navy there is no mistaking the bell bottom trousers with flab on the back, "dixie cup" hat and chevron with crow on the left sleeve.

in 1914, the portuguese uniforms were given by the british army, so they were equal to the british army uniforms
