I don´t know her, I just now that this picture has taken in my favourite hotel in Majorca, the Formentor. It was first opened in 1929, and about five years later this pic was taken.
I find it most inspiring, not only because of her outfit, but because of the shape her body draws against the background. Like you´ve showed us in your shots, most of the times it´s not about the clothes, but of the attitude, and I think this is a clear example of it.
