I brought a S and it is huge! It's looks like a Large on me!
Not pleased at all, I spent £8 on a top that i will wear once for a party then probably never wear it again!

I've been wanting this t-shirt for ages and got it when the price came down although I would say it would have been worth paying the £11.99 for it even after it went down to £7.99. The fabric isn't thin and yet not so thick it's heavy. It feels good quality and the logo is very bright and bold.
I took advice from another review and bought a size smaller and it fits perfect. I got a small and I'm a size ten. Without reading that review I might have drowned.
Only down side was the blue is a lot darker than i thought it would be.
Still I love it and would recommend it to anyone who wants to be superman!

a really good quality t-shirt, not too thin which is good. the colours are really great, bright and bold. definitely glad i bought it
