the very trivial but mind consuming things I think about

anyone else noticed that very frequently on clothing items with 2 colours and stripes, these stripes tend to be around 3/4 cm wide - it's like an unofficial stripe standard. I noticed this today for the umpteenth time as my bub and I were both wearing stripes of the same width. There must be something behind it - is it related to the traditional french jersey? or naval uniforms? and why that width? I might go google it....
