Wearing suspenders or braces to hold up pants; dressed or supported with galluses.
From 'gallus' or 'galluses' (suspenders), derived from the plural of the Latin 'gallus' (a rooster or peg), which metaphorically referred to straps that hold things up, popular in American English by the 1800s.
The word 'gallused' reveals how Americans loved colorful descriptors for everyday items—what the British called 'braces,' Americans called 'galluses,' probably because they resembled the straps used on farm equipment and barnyard gear.
