Looking like something straight out of a gents outfitters from the 60s is this Adidas Freizeit polo shirt.
Available in an unusual shade of mint, it’s a three-button polo shirt with contrasting collar and pocket, along with elasticated cuffs and waist. And as near touch, you even get Adi Dassler’s initials on the pocket. Though if your initials are also "AD", you could end up looking a little like Delboy!
Available online, you can pick one up for around £50.
