What size would you recommended for a usually *M* 14 year old boy who does not want it baggy?

Loving the shirt... But on reading a review on this shirt I followed his advice and brough the wrong size! Buy the size most comfatable for you...

I absolutely love this t-shirt, brill for jus chillin in!
the thing i was disappointed with is the fact that it's a bit too large considering i ordered a M, it's more of a large...for future buyers i reccomend gettin' a smaller size than your usual
