Answer: (1) Because of the appearance of clothing design, there are requirements for clothing decorative accessories and various new ornaments. Modern fashion design appeared in France around 1905. Paul Brett became the first fashion designer in the modern sense and the earliest fashion designer in the world. His exploration completely changed the almost unchangeable appearance of women's clothing design and created a colorful new era of women's clothing. Increasing social activities are also stimulating factors of demand, so French jewelry design has experienced unprecedented prosperity. The changeable hairstyle puts forward new requirements for the design of hair clips and headdresses, and the demand for various bracelets, necklaces, earrings, brooches, rings, bow ties, cufflinks and belts has also increased greatly. Therefore, many designers have introduced some characteristics of the "decorative art" style, such as the pattern style of ancient Egypt and the East, simple geometric modeling style, bright color plan and so on. , into the design of jewelry and clothing accessories.

(2) This design reached its climax in the 1920s and 1930s, and some outstanding jewelry designers appeared. Gerald Sandars is one of the typical representatives. His design is very distinctive, imitating mechanical geometric patterns and adding complex and expensive materials. Jean Du Nan, a master of lacquerware design, makes jewelry and clothing accessories with lacquerware, which has a strong oriental color and is very popular. R. Larik uses very bright metal materials to design jewelry and clothing accessories, uses plant patterns and decorative female bodies as decorative motives, and uses silk as a tie, which is also excellent. Coco chanel, a French fashion giant, used exaggerated and disproportionate jewelry to meet the needs of special customers. Other important French designers include Raymond Tabelli, Paul Brandt, Alec Walter, Gabriel Anji-Rousseau and Eliza Sparelli.
