Claire McCardell is often credited with the creation of the American Look; the casual yet stylish approach to dressing, which has endured for years since. In What Shall I Wear?, originally published in the 1950s and, since then, increasingly sought after, McCardell emphasises how important it is to wear what suits, and is comfortable. McCardell pioneered several fashions still seen today. For example, she was the first designer to put models in ballet flats, which then became one of the biggest trends since high heels. What Shall I Wear? will become a staple on the shelf of any aspiring fashionista or designer.
