Usually size information is given on the description of the product page, but unfortunately, it's in Chinese. Since we have different clothes from various factories, clothing size varies.
Please contact our customer service using live chat, and give us your body measurements (Height, Weight, Shoulder and Chest size), we can quickly suggest you a size which will fit you.
If you don't have the information right now, take your time. Once you get this information, chat with our sales support team, they will help you to find the size anytime :)
