The dress June is wearing is reminiscent of the dress worn during the "orange blossom" scenes.
While it may not be from the film, fits so very well here.

The gown was by well known designer Johanna Mathieson. Various photos were sent to all major newspapers.

The descriptive caption read:
June Marlowe, Universal leading lady, wears this charming gown made of imported French silk embroidered with silver scallops. The gown was used in Miss Marlowe's latest picture, "Wild Beauty", a Universal-Jewel directed by Henry MacRae. From an original design by Johanna Mathieson.
