(and other ladder-climbers),
Put a “modesty snap” in your kilt to hold the front to the back while up high. The curious down below will soon get tired of looking.
(in British English: a press stud sewn to the middle of the inner front apron and to the middle pleat at the back will keep pryong eyes out of your kilt, and you’ll be able to get on with your work in peace. The stud can be released for everyday wear, of course.)

Don’t you feel cold without that comforting thickness of good wool round your lower back?
