1. Fashion

2. The fashionable silhouette in the early 1900s was that of a mature woman, with full low bust and curvy hips. The "health corset" of this period removed pressure from the abdomen and created an S-curve silhouette.[1]
Blouses and dresses were full in front and puffed into a "pouter-pigeon" look over the narrow waist, which sloped from back to front and was often accented with a sash or belt.
Skirts brushed the floor, often with a train, even for day dresses, in mid-decade.
Around 1908, the fashion houses of Paris began to show a new silhouette, with a thicker waist, flatter bust, and narrower hips. By the end of the decade the most fashionable skirts cleared the floor and approached the ankle. The overall silhouette narrowed and straightened, beginning a trend that would continue into the years leading up to the Great War.

3. Lingerie dresses
Frothy washable day dresses of translucent linen or cotton, called lingerie dresses, were worn in warm climates. These were trimmed lavishly with tiny pintucks, lace insertions, embroidery, and passementerie. Their origins lie in the artistic or aesthetic dress and the adoption of the uncorseted tea gown for wear outside the home.

4. Hairstyles and hats
Huge, broadbrimmed hats were worn in mid-decade, trimmed with masses of feathers and occasionally complete stuffed birds, or decorated with ribbons and artificial flowers. Masses of wavy hair were fashionable, swept up to the top of the head (over horsehair pads called "rats" if necessary) and gathered into a knot.[6] Large hats were worn with evening wear.
By the end of the decade, hats had smaller drooping brims that shaded the face and deep crowns, and the overall top-heavy effect remained.

11. 1920’s
The 1920s was the decade in which fashion entered the modern era. It was the decade in which women first liberated themselves from constricting fashions and began to wear more comfortable clothes (such as short skirts or pants). Men likewise abandoned overly formal clothes and began to wear sport clothes for the first time. The suits which men still wear today are still based, for the most part, on those which were worn by men in the late 1920s.
The 1920s were characterized by two distinct periods of fashion. The early 1920s were relatively conservative in nature and changed progressed slowly as many were reluctant to adopt the new styles. From 1925, the styles that have been associated with the Roaring Twenties were passionately embraced by the public and would continue characterize fashion until late in 1930

12. In the late 1920s is the one which is typically associated with flappers and the Jazz Age. The flappers often danced and were looked down upon by some of the more shyly dressed women. These women were always noticed by the men. In 1925, the waistline completely disappeared and cloche hats (without rims) became all the rage. For women, the rest of the 1920s would be characterized by a bustless, waistless silhouette. In the latter part of the decade, dresses were cut to fit closely to the body in order to promote a youthful elegant look. Aggressive dressing-down was mitigated by feather boas, embroidery, and showy accesories. The flapper style (known to the French as the 'garçonne' look) became very popular among young women during this period. The cloche hat was widely-worn and sportswear became popular with both men and women during the decade. Women's coats were mostly long until around They often wrapped to just one side fastening which was a feature of the garment as either a huge button or some complex tab and buckle. Fair Isle patterns became very popular for both sexes. Heels, at the time, were often over two inches high and Coco Chanel helped popularize the two-tone shoe, one of her trademarks. Hemlines continuously rose until 1928 when they reached slightly above the knee
