Leisa, most of the Barbizons I've had with that label I've dated to the mid to late 50s. But I don't think their labels changed all that much. This style has the side metal zip, scalloped neckline and hem, and the really wide straps, right? (I get my Barbizon styles mixed up sometimes....) Pretty sure it's that 50's timeframe, even though I think they didn't discontinue using side metal zippers until the early 60s. Love these slips, btw--nice enough to wear under a suit jacket just peeking out the top, IMHO!
