Question

A tailor is to a seamstress, as an_ is to an actress

Answer 1

Answer:

Seamstress is the term that is still used:

a woman who can sew and make clothes or whose job is sewing and making clothes. (OLD)

It derives from seamster, which is gender-neutral but also quite rare ( see Ngram ):

seamstress (n.):

1640s, with -ess + seamster (also sempster), from Old English seamestre "sewer, tailor, person whose work is sewing," from seam. Originally indicating a woman, but after a while the fem. ending -estre no longer was felt as such and a new one added.
