Unfortunately there is no standard size for clothing as measurements are not the same across different brands and manufacturers. We try to provide as much information as possible so you can make the correct choice. Feel free to contact us should you require personalized help.
Each item has a size chart (just click 'size chart' right next to 'select size' on the product page) which provides detailed measurements. We advise measuring yourself against the chart to determine the best size. Also please leave a review with fit information after you purchase so future buyers have more info!
We are not going to provide a chart which shows conversions of U.S. sizing to other countries as they are inaccurate. Going by the measurements is the best way to determine if an item will fit you.
