The gold pair is almost dateless because that style looks essentially the same for about 20 years beginning in the mid 30s (with the exception of 1942-46 when they weren't making gold leather evening sandals in the U.S., or anywhere for that matter...) The heel looks postwar to me, and the toe shape is pretty round, so I would suggest about 1948 - 52 - that pinky beige lining to the upper is also very typical late 40s - early 50s.
The purple pair are also about 1948-52. I think I recall seeing that exact pair in a Montgomery Ward's catalogue from about 1951... I might still have that issue in fact. That style of shoe is not made for a hot and sexy young woman - it was intended for a middle aged, middle class woman and I see her feet swelled and she cut the leather at the throat to expand the size.
