Size 4 typically refers to a clothing size commonly used in women's apparel. In the United States, a size 4 generally corresponds to a bust measurement of 34 inches, a waist measurement of 26 inches, and hip measurement of 36 inches. This size is part of a numerical sizing system that helps consumers find garments that fit their body dimensions. In other countries, such as the United Kingdom, a size 4 may differ slightly. For instance, a UK size 4 is often equivalent to a US size 0 or 2. Understanding these differences is important for international shopping and sizing accuracy, especially when purchasing items from brands like Zara or H&M.
