Hello, I am considering a dress by Geoffrey Beene. It has a huge circle skirt and pleating, looks very late '50s/early '60s. However, it has the "Geoffrey Beene Boutique" label, and in one place on VFG it says he didn't start that label until 1972. However, two very prominent vintage sellers are saying it's '60s. Can anyone confirm one way or the other or clear this up for me?
