Happy with the tshirt but if I had purchased the size adidas said they were 98% sure would fit.... It wouldn't have. This is a tight fit and the site recommended a size smaller!!! Also track tops and trainers vary in size I'm a small bit some track tops fit some don't, I'm a 6.5 and most trainers are to narrow but some aren't.. Adidas you really need to get consistency with your sizing cos the look of some of the stuff is great but it's always a gamble if it's going to fit.
