PSA to all historical fiction/fantasy writers:
A SEAMSTRESS, in a historical sense, is someone whose job is sewing. Just sewing. The main skill involved here is going to be putting the needle into an out of the fabric. They’re usually considered unskilled workers, because everyone can sew, right? (Note: yes, just about everyone could sew historically. And I mean everyone.) They’re usually going to be making either clothes that aren’t fitted (like shirts or shifts or petticoats) or things more along the lines of linens (bedsheets, handkerchiefs, napkins, ect.). Now, a decent number of people would make these things at home, especially in more rural areas, since they don’t take a ton of practice, but they’re also often available ready-made so it’s not an uncommon job. Nowadays it just means someone whose job is to sew things in general, but this was not the case historically. Calling a dressmaker a seamstress would be like asking a portrait painter to paint your house
A DRESSMAKER (or mantua maker before the early 1800s) makes clothing though the skill of draping (which is when you don’t use as many patterns and more drape the fabric over the person’s body to fit it and pin from there (although they did start using more patterns in the early 19th century). They’re usually going to work exclusively for women, since menswear is rarely made through this method (could be different in a fantasy world though). Sometimes you also see them called “gown makers”, especially if they were men (like tailors advertising that that could do both. Mantua-maker was a very feminized term, like seamstress. You wouldn’t really call a man that historically). This is a pretty new trade; it only really sprung up in the later 1600s, when the mantua dress came into fashion (hence the name).
TAILORS make clothing by using the method of patterning: they take measurements and use those measurements to draw out a 2D pattern that is then sewed up into the 3D item of clothing (unlike the dressmakers, who drape the item as a 3D piece of clothing originally). They usually did menswear, but also plenty of pieces of womenswear, especially things made similarly to menswear: riding habits, overcoats, the like. Before the dressmaking trade split off (for very interesting reason I suggest looking into. Basically new fashion required new methods that tailors thought were beneath them), tailors made everyone’s clothes. And also it was not uncommon for them to alter clothes (dressmakers did this too). Staymakers are a sort of subsect of tailors that made corsets or stays (which are made with tailoring methods but most of the time in urban areas a staymaker could find enough work so just do stays, although most tailors could and would make them).
Tailors and dressmakers are both skilled workers. Those aren’t skills that most people could do at home. Fitted things like dresses and jackets and things would probably be made professionally and for the wearer even by the working class (with some exceptions of course). Making all clothes at home didn’t really become a thing until the mid Victorian era.
And then of course there are other trades that involve the skill of sewing, such as millinery (not just hats, historically they did all kinds of women’s accessories), trimming for hatmaking (putting on the hat and and binding and things), glovemaking (self explanatory) and such.
TLDR: seamstress, dressmaker, and tailor are three very different jobs with different skills and levels of prestige. Don’t use them interchangeably and for the love of all that is holy please don’t call someone a seamstress when they’re a dressmaker
