The most well known scouting uniform in the history of America, Boy Scouts wear a tan shirt and green pants with a red and yellow neckerchief that distinct them from the younger scouts.
On that site, the Boy Scouts of America provide details about the shirt, pants, belt, socks, cap, neckerchief, and neckerchief slide, as well as some photographs.
Each unit may have different uniform expectations, with some expecting all of the aforementioned gear while others exclude the neckerchief and/or hat.
The youngest and newest troop members are the Tiger Cubs, who wear a navy blue uniform with a blue and orange coordinating neckerchief.
Like the other ranks that go before it, the Bear Cub uniform is basic navy with a special Bear Cub neckerchief and sky blue cap.
Neckerchief and slide: Neckerchief must be folded into a triangle shape and each side must be secured with a slide.
For example, in the U.S. the uniform started with a blue skirt and matching blue neckerchief over a white blouse.
There are several styles of Boy Scout neckerchiefs and neckerchief slides that can be seen at Scout Stuff.
Again using the standard navy blue Cub Scout uniform, the Wolf rank includes a new neckerchief and cap.
These 1919 era uniforms were complemented by a khaki colored crowned hat, neckerchief and webbed belt.
