I bought this T-shirt in a small size as that was the same size as my usual clothing. It was VERY small indeed and I had to return it and eventually bought the large size which is equivalent to an English size 14 which I have never worn in my life! Don't get me wrong, this is a really great T-shirt for those aging rockers who refuse to lie down and die but be careful as to which size you buy as, if you buy your usual size you won't be able to breathe properly! I should say that the merchant from whom I bought the item was justlovemytshirt.com and their customer service was excellent - friendly and efficient - and I intend to wear the T-shirt this weekend with my favourite skinny jeans at which point my husband will pretend that he doesn't know me!
