This report provides an analysis of the UK fashion industry, focusing on the application of Porter's Five Forces model to assess the competitive landscape. The report examines the threat of new entrants, highlighting the high capital requirements and brand strength of existing companies as barriers. It evaluates buyer power, noting the abundance of choices and the ease with which customers can switch between brands. Supplier power is deemed relatively low, as fashion companies do not heavily rely on suppliers for raw materials. The threat of substitution is considered low due to the high investment needed to start a new company in this sector. The report also assesses the high level of competitive rivalry within the UK fashion market, where similar products and pricing strategies create intense competition. The analysis is supported by references to academic literature on sustainable supply chain management and corporate social responsibility in the fashion industry, concluding with an overview of the industry's growth and high competition.
