Swimming is an international sport, and women's swimwear is manufactured all over the world, including Europe and the United States. If you're located in the U.S. and buying swimwear from a European company, you may not know how your American swimsuit size compares to your European size. However, there is an easy way to find out.
Find the size of a swimsuit you already own that fits you well, by looking at the tag.
Visit a website that offers an American-to-European swimwear size conversion chart. Two options are www.swimmersden.com and www.blk1.com.
Find your American size on the chart; for example, size 8 (a medium).
Scan the chart to find the sizes for the country you're buying the swimsuit from. For example, the Italian equivalent of an American size 8 is 42.
If you don't have access to the Internet, you can estimate your size. A rough guide for French, Italian and German sizes is to add 30 to whatever your American size is. For example, an American size 6 (a small) plus 30 roughly equals a European size 36. For British sizes, just add 2. For example, an American size 12 (a large) plus 2 equals a British size 14.
British, French, German and Italian swimwear sizes all differ slightly. If possible, it's best to convert to the sizes of a specific country rather than estimate.
