Normally I’d associate a pretty outdoor nude of this vintage with a nudist camp setting, or at least with crypto-porn wearing that camouflage. But the brilliant smile while trying to balance on indoor shoes, the fully dressed men laughing in the background, and the bulky square equipment case one of them is carrying, make me think “model” rather than genuine nudist:

Update: Thanks to commenter Ssspender for providing a model ID (Joan Blondell) and a link to a much clearer zoom crop of the same image, from a BBS file image that backs up his model ID:
