Kilt Breeks/Breeches? Anyone recall this

[neloon]

You may appreciate two advantages of the undertrews:-
1.Everyone knew what was concealed so "the question" did not arise.
2.It was not uncommon for the kilt to be removed in public without any embarrassment (see the picture referenced in my first link above). Boys, especially, could doff their kilts if a tree needed to be climbed or a race run. Games athletes likewise if the pole vault was getting too high!

It should also be noted that, away from the big cities, things were more variable. In a travel diary called "England from a back-window; with views of Scotland and Ireland" (available as an ebook), a Boston journalist in the 1870s writes of Highland Dress
" ...The dress consists now of a sack-coat, — instead of the plaid
waist of former times, and the long plaid wrapped about the
body for protection, — a kilt, or a yard or two of tartan gath-
ered in tucks at the upper edge, and wound about the hips,
and fastened at the waist, and of sufficient width to permit it
to reach within one or three inches of the knees. Under
this is a pair of muslin or woollen drawers of sufficient length
to cover the thighs, but hardly long enough to be re-assur-
ing to the sensitive observer on a windy day..."
In UK-speak, "muslin" would be a ridiculous clothing material so I suspect we need a US translation.
