Phantom Thread passes the bechdel test surely? Off the top of my head there's lots of chat about work between Cyril and the seamstresses, and there's also the conversation between Alma and the princess.
Also: (mild spoiler)
imo it's kinda silly to imply this film is problematic in its depiction of women when it features a female protagonist who ultimately wields all the power in the relationship.
Edit: OK, I understand the criticism better now http://www.riotmaterial.com/p-t-andersons-phantom-thread-couldnt-come-at-a-worse-time/
