I wonder if this photo was tinted in some way. That would explain why the woman's shoes match the umbrellas so perfectly. Also most of the tones are in orange and blue. The man is wearing blue clothes and some people in the mid-ground are wearing the same blue. Yes you certainly can see Lanvin and the Carlton Hotel.
This is actually my friend's parents (the last time I saw them they were similarly elegant, poised, and well dressed well into their seventies?)…posted by his amazing wife; I emailed her immediately to ask if I could paint this photograph. I will send a photo when its finished!! It has beautiful perspective, with the complimentary blue and orange hues. Oh my, so excited.
They look square but still very "modern". Things were more layered and repressed back then and it gave people more radiant energy and style. They couldn't/didn't just let it all hang out. She knows how hot she is and her leg positioning is classic pinup. I like how his espadrilles coordinate with his trousers and shirt. ;-)
