Overall, I'd suggest the site Job Evaluator. That link leads to the table of contents, which lists 120 jobs in alphabetical order.
Within that, this link is for Tailors:
Tailor Career: Salary, Outlook & 85+ Things You Have To Know
I did read some of that, it sounds reasonable and authentic. Below is a copy of the table of contents; I should think this will provide all the detail you need. 1950 would be similar, just pick the skills unlikely to change, and skills that don't depend on any computers or other modern technology.
As for salary, you can scale 2022 salaries back to 1950 using the Consumer Price Index, or if very early, by comparing something like gold prices or even what a day's wages could buy in terms of grain or something.
For 1950, multiply by 8.5%; so the median annual wage given for tailors in 2022, $41K per year, would be $3,485 per year in 1950. But would buy approximately the same things in terms of housing, food, clothing, entertainment, etc. (Presuming the things existed in 1950.)
So typical duties include hand-sewing, alterations (spelt "alternations" in the article), repairs, etc, besides custom fitting and making new clothes from scratch. A tailor requires a strong knowledge of sewing various kinds of stitching, and understanding of many fabrics (how they sew, cut, how they feel and what they weigh, how they breathe, wrinkle, insulate, the environments they are best in.)
But read for yourself.
