UK sizes refer to a standardized system used primarily for clothing and footwear in the United Kingdom. These sizes help consumers find the right fit when shopping for items like dresses, trousers, and shoes. For example, women's clothing sizes typically range from UK size 6 to UK size 18, while men's sizes often start from UK size 34 for trousers. In the UK, shoe sizes are measured differently than in many other countries. A standard UK shoe size for adults usually ranges from UK size 3 to UK size 12. It's important to note that sizes can vary between brands, so trying on items is recommended for the best fit.
