This is a late 1960's Ben Zuckerman dress, in a very pale celery green. The dress is simple and rather stark, but is tailored expertly and has buttons running from the neckline to the waist.

This dress is much more youthful than the Zuckerman designs of the 1950's, which reflected the change in fashion in general during the mid to late 1960's.
