In the world of online shopping, it’s really very easy to get items you want from any part of the world. But there is a little problem since different country follow different standard of sizing info. Like the sizing index that US follows is not recognized in Asia and so on. Medium size in US is somewhere equivalent to Large size in Asian clothing measurement.
I hope this chart will help you to get idea how size/tag differs from country to country.
