Prorsum

went looking into Burberry, the English clothing brand, famous for their iconic plaid.

Prorsum, on their logo, a Latin form: towards, forwards.

Turns out Burberry made a movie about Thomas Burberry:

Thomas Burberry invented the fabric gabardine and revived the name (which had been used in the Middle Ages to describe, like, overcoats). Mallory was wearing gabardine when he died trying to summit Mount Everest (he still is wearing gabardine. If you’re morbid, you can find photos of his body and see how well the Burberry is holding up after a hundred+ years).
