Was "Seamstress" used as a euphemism for sex workers in real life?

Terry Pratchett's Discworld series uses "seamstress" as a euphemism for sex worker. Prior to the publication of the series, was it used in real life this way?

It sounds very plausible, but neither Wiktionary nor the Online Etymology Dictionary mentions it.

It is mentioned in the Encyclopedia of Prostitution and Sex Work Vol 2 ISBN 0-313-32970-2 Pub 2006 Greenwood Press

SEAMSTRESSES. "Seamstress" was a euphemism for "prostitute" in census records and other documents of the 19th century in the United States. Historical documentation showing several "seamstresses" sharing common living quarters may generally be assumed to represent a brothel. Whether this occupation was reported by prostitutes or supplied by census enumerators and other officials remains speculative, although potential reasons for both are easily understood. Legitimate uses of the term should not be confused with the codified use. Other historical and modern euphemisms exist, including laundressess and actressess.

New Essays on Poe's Major Tales by Kenneth Silverman, Cambridge University Press 1993 also states:

Terms like "shopgirl" and "seamstress" were mid-century euphemisms for women whose chief source of income was their bodies.

This website also discusses the issue with reference to an older work by Charles Horne

In John Cleland's Fanny Hill Mrs Cole's establishment poses as a "millinery shop". A milliner's or mantua-maker's establishment was often likened to a house of prostitution, probably an accurate public perception.

A good many of the fallen women whose bastard children were put into the Foundling Hospital were seamstresses. Millinery and dressmaking were a kind of introduction to the prostitute's trade. What trial records show is that when prostitutes were brought into court (usually for stealing a gentleman's watch while his trousers were down), they would describe themselves as apprentices to a mantua-maker, or as being at one time a mantua-marker before they were led astray. A character witness for a prostitute will commonly be a mantua-maker, but I think many judges and juries realized that this mantua-maker acted as the "aunt" at the head of a small-time ring of streetwalkers. The professional mantua-maker often took in lodgers to supplement her income, and the real situation, often as not, is that she would have a few girl "apprentices" who mended stolen clothes and made new clothes from stolen textiles while they are not otherwise engaged picking up men in the street and bringing them to their mistress's upstairs rooms. It was not uncommon for a gentleman to go into a milliner's shop and have sex with one of the girls then and there. Though dressmaking could of course involve a high degree of professional skill, it also provided good cover for both prostitution and fencing stolen goods. Very large quantities of linen and silk, plus ribbons and lace etc., were regularly stolen from warehouses, and found their way to mantua-makers, milliners, and tailors. Tailors and milliners often acted as pawnbrokers, which to a great extent meant dealing in stolen goods. They operated on the boundary between the underworld and the respectable world.

The occupation of millinery or mantua-making was widely regarded as just a cover for prostitution. Charles Horne in Serious Thoughts on the Miseries of Seduction and Prostitution (1783) warned parents not to allow their daughters to become milliners, mantua-makers, or workers in the various clothes trades because they were "actually seminaries of prostitution".

I attach a Census image from 1881 of Devonshire Street in St. George in the East, London which has a number of properties where the young female occupants (all lodgers) from many countries have a range of occupations such as dressmaker, laundress, etc. but who were almost certainly prostitutes.

Emily Brown at No. 19 even has a gentleman visitor who presumably chose not to reveal his name which is registered as "N.K".

Interestingly Sarah Pipman on the bottom line does not have a euphemism.

In Cambridge (England) there used to be a special police force that had the power to arrest women “walking in the company of a member of the university” and imprisoning them in the “spinning house”, where they were actually set to work spinning. This continued until as late as 1891.
