The role of a lady's maid is similar to that of a gentleman's valet.
[1] Traditionally, the lady's maid was not as high-ranking as a lady's companion, who was a retainer rather than a servant, but the rewards included room and board, travel and somewhat improved social status.
In the servants' hall, a lady's maid took precedence akin to that of her mistress.
A lady's maid would also remove stains from clothing; sew, mend, and alter garments as needed; bring her mistress breakfast in her room; and draw her mistress's bath.
However, she would not be expected to dust and clean every small item, as that would be the job of a housemaid.
