Vintage Oscar De La Renta boutique dress ID help

[Lady Atkins]

Hello. I found this dress in the Los Angeles area quite some years ago. I was only able to find one ad with one similar in material but but in style. Does anyone have any idea the appropriate year of this ? Thanks.

1977-ish is my estimate.

May we please see the label?

I'm still thinking 1977 or so.

The union label puts it in the 1974-95 window

It is the same label as one in our Label Resource
