Where to find sewing pattern reference?

The more I do cloth simulation, the more I realize that one needs to know how clothes are made in real world to correctly simulate them in a 3D software.

I know nothing about sewing. Therefore I try to find some sewing patterns online:

But google usually leads me to a bunch of low quality pinterest result, or e-shop that sells clothes. Is there something like Blenderkit or Polyheaven, but for sewing patterns? Like a database colleting the most common patterns?

I personally gather Free reference PDF Books on Victorian patterns, to use in Marvelous Designer… to get better results in your search try…

FREE Clothing Patterns Online -Pinterest <<
adding -Pinterest to your search will ignore anything from Pinterest!

EXAMPLE of the above…
