I purchased an Adidas jersey for my son last summer. I ordered a Large and UKsoccershop sent me a shirt labeled US Large. This summer I ordered another Adidas jersey in a Large. This time, they sent me a Medium and said that they refused to return it because a US Medium is a UK Large, despite the fact that Adidas sizes their shirts on the US system. They refused to do anything to remedy the situation. I will never buy anything from this shop again!
