ELI5: How does compression clothing work?

There seems to be a lot of data confirming that compression clothing (tights, socks, sleeves, etc.) improves circulation. But my understanding is that compressing blood vessels would inhibit circulation. How does this work?
gpt
It compresses the small capillaries and vessels near the surface, forcing/diverting more blood through muscles and organs where it is needed.

You don't circulate more overall, but you are circulating more where it's needed.
