The ladies look to be standing by the stairs on the right side of the DuPont Gun Club clubhouse. I don't think it is the same shoot; labeled only July 4, 1913 and the ladies are in white

The ladies of the Nemours Club and the ladies of the Fox Gun Club did visit each other for shoots; October 1913 in Forest & Stream

Frank apparently has an image of a DuPont - Fox shoot from 1915
