Cover-Slut

Flicking listlessly through my OED I came across the word cover-slut, which means "something worn to cover sluttishness, an apron or pinafore", a verbal corollary to the phrase All fur coat and no knickers. The Universal Dictionary of Science, Art, Literature and Practical Mechanics of 1829 puts it more alliteratively: "Cover-shame and cover-slut are contrivances to conceal infamy and sluttishness."  But judging by the magazine rack at my nearest Tesco Metro (etymologically Tesco mother), I feel the noun could usefully be reassigned.

A gallimaufry of cover-sluts

P.S. The only actual usage of cover-slut I was able to turn up comes from Hall's Ireland: Mr & Mrs Hall's Tour of 1840 and is too deliciously domineering not to reproduce in full.

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. ' Oh, then, I'm not fit to be seen; hadn't I better tidy myself a bit? — but aisy! sure when I throw on my cloak no one will know what I am,' is a too frequent observation; and away they go, shrouded from head to foot in this woollen hide-all.
