Cover-slut

Nor let your women there appear / With dirty ſmock-ſleeves, foul head-geare, / With Cover-ſlut from Neck to Toe, / As Maids to morning Lectures go.

The Irish cloak forms very graceful drapery; the material falls well, and folds well. It is usually large enough to envelop the whole person; and the hood is frequently drawn forward to shield the face of the wearer from sun, rain, or wind. Yet we would fain see its general use dispensed with. A female in the lower ranks of life cares but little for the other portions of her dress if she has "a good cloak;" and certainly her ordinary appearance would be more thought of, if the huge "cover-slut" were not always at hand to hide dilapidations in her other garments.

Fie, madam, you'll ruin the sex! Husband, say ye? A mere thing—a cover-slut of custom!
