Ethnic clothing covers a variety of different styles, but in my personal opinion I think it originates from culture within tribal backgrounds which have been adapted into different patterns.
There are many types of ethnic styles throughout high-street shops and markets. Currently I feel cardigans and jumpers adapt this style best. This is due to the complex patterns which are adapted through the knit of the fabrics. Generally an ethnic pattern will develop vertically through lines stripes and dots. Most garments will include bright colours and bold styles.
Fair trade adapts ethnic styles to the clothing. Ethnic clothing aspires through history and bright coloured patterns. A common cut of clothing categorised as ethnic is the poncho.
