In his younger days, my grandfather wore little leather thongs pulled tight on the sleeves of his upper arms, so that his cuffs would not pick up ink, brushing what he was writing. I've heard someone else describe ribbons used for the same thing.
I am wondering if there are standard names for those thongs or ribbons. Is "garter" the right word? Are there others? I see "tie-up" in the OED, defined "(makeshift) garter", with two citations from the 1970s, one of which is in connection with shirts.
