The outfits below are at once relaxed and stylish—and this is why the 1960s is one of my favourite fashion eras! The coordinating skirts and tops were available in different colours, shown as thumbnails on the same catalogue page as the main photograph.
The garments are all made of "triacetate", a "semi-synthetic" material made of chemically treated wood pulp. Like fully synthetic materials, triacetate was easy to care for, and like natural fibres it was breathable. In other words, "carefree"!
