‘There is little difference in design between a day frock and an afternoon frock – but the material is usually a little richer. Of corse you can wear a suit in the afternoon, too, but for later afternoon nothing is more useful than a frock which may be worn for cocktails or for dinner as well. Black is the best color for it – in any material. If you can have only one afternoon frock i should always advise you to have it in black. And the most useful design is a dress with a decollete – and a bolero or spencer. Any sort of material is good – from wool to lace. Any sort of bodice and any kind of skirt – slim or full, it depends on your kind of figure and the kind of life you lead’ – Christian Dior, The Little Dictionary of Fashion.
