Fashions in the early years of the decade reflected the elegance of the First Lady, Jacqueline Kennedy. In addition to the pillbox hat which is discussed in detail below, women wore suits, usually in pastel colours, with short boxy jackets, and oversized buttons. Simple, geometric dresses, known as shifts, were also in style. For evening wear, full-skirted ballgowns were worn; these often had a low décolletage and had close-fitting waists. For casual wear, capri trousers were the fashion for women and girls.
Stiletto-heeled shoes were widely popular.
As the suits drifted away from pale, toned shades, menswear was now bright and flamboyant. It included frills and cravats, wide ties and trouser straps, leather boots and even collarless jackets. Ties were worn even five inches wide, with crazy prints, stripes and patterns. Casual dress consisted of plaid button down shirts with comfortable slacks. 
The mid 1960s
After designer Mary Quant introduced the mini-skirt in 1964, fashions of the 1960s were changed forever. The mini was eventually to be worn by nearly every stylish young female in the western world.
The mini dress was usually A-line in shape or a sleeveless shift.
In 1964, French designer Andre Courreges introduced the "space look", with trouser suits, white boots, goggles, and box-shaped dresses whose skirts soared three inches above the knee. These were mainly designed in fluorescent colours and shiny fabrics such as PVC and sequins.
The leaders of mid 1960s style were the British. The Mods were characterized by their choice of style different from the 1950s and revealed new fads that would be imitated by many young people. As a level of the middle social class known as the Mods, controlled the ins and outs of fashion in London, 1960's fashion set the mode for the rest of the century as it became marketed mainly to youth. Modernists formed their own way of life creating television shows and magazines that focused directly on the lifestyles of Mods. British rock bands such as The Who, The Small Faces, and The Kinks emerged from the Mod subculture. The Mods were known for the Modern Jazz they listened to as they showed their new styles off at local cafes. They worked at the lower end of the work force, usually nine to five jobs leaving time for clothes, music, and clubbing. It was not until 1964 when the Modernists were truly recognized by the public that women really were accepted in the group. Girls had short, clean haircuts and often dressed in similar styles to the male Mods.  The Mods' lifestyle and musical tastes were the exact opposite of their rival group known as the Rockers. The rockers liked 1950s rock-and roll, wore black leather jackets, greased, pompadour hairstyles, and rode motorbikes. The look of the Mods was classy; they mimicked the clothing and hairstyles of high fashion designers in France and Italy; opting for tailored suits, which were topped by anoraks that became their trademark. They rode on scooters, usually Vespas or Lambrettas. The Mods dress style was often called the City Gent look. Shirts were slim, with a necessary button down collar accompanied by slim fitted pants. Levi's were the only type of jeans worn by Modernists. Flared trousers and bellbottoms led the way to the hippie stage introduced in the 1960s. Variations of polyester were worn along with acrylics.
