Whilst representing the Great Britain Diving Team Tom Daley has progressed from skinny school boy to rather muscular man.
The photo shows him as adult but younger than he looked gaining a bronze Olympic medal yesterday. I'd guess the photo to be 2 0r 3 years old.
British Gas has sponsored the Great Britain diving team and provided team suits.
The British Gas suits tend to be worn at the World Championships as the British Olympic Committee issues it's own uniforms for athletes.
My guess is that this is a British Gas sponsored British Diving Team suit of about 2019 when Tom Daley dropped out of the World Championships due to a hip injury.
