High fashion and streetwear are two styles that have a large effect on the public due to various dominating fashions. They have also begun to test conventional limits. High fashion is generally considered as being more expensive than casual wear, but some high-end brands have become more affordable over time. High fashion often involves use of luxury materials such as silk or velvet, while streetwear tends to be made from cheaper fabrics such as cotton or polyester. Both high fashion and streetwear tend to influence each other because major labels will often copy successful designs from smaller brands. Also see: Top 10 Brands That Influence Style.
