Mathematical geometric shapes formed the basis of the structure of most Art Deco design patterns. They were generally seen to have trapezoidal, zigzag and triangular shapes, chevron patterns, stepped forms and sunburst motifs . Floral patterns and images of botanical objects were also part of the design. Plain or geometric fabrics were mostly used in Art Deco. Smooth fabrics such as wools, silks that lacked texture were used. Cushions sometimes covered in fabrics that contrasted with the rest of the body were sometimes used to enhance boldness. Art Deco reflected a shift to lighter and more neutral shades that had a metallic undertone. Popular colors in this design are such shades as black, gray, silver, white and brown variations. Bolder colors such as yellow, red, gold, green and blue were used minimally and were muted. Exotic pastels were a popular accent color at the time when Art Deco was popular. Art Deco fashion formed the next fashion look after the decline of art nouveau. It had two phases between 1910 to 1924 and between 1924 to 1930 . The former was built around neoclassical/ peasant designs while the latter was more minimalistic, with a modern touch. The first phase was led by Paul Poiret . He launched his first works in 1908 which was slim, simple, high waisted dresses that were delicately layered and exotic in style. His use of shades of pink, purple, blue, green and gold was inspired by his interest in Fauve paintings. In 1911, Paul organized the thousand and one night Ball.
