The style of the green suit photo suggests that it is quite an old picture.
The green suit is not just matt but appears to be faded matt. I suspect that this is an old faded suit photographed a long time ago, probably with a film camera (the pixels don't break up easily. My guess is that this is an early 1980's nylon suit.
There are 2 lines of text on the red suit, and some white text/logo under the swimmers left hand. The photo breaks up as soon as it is zoomed in on, suggesting a basic digital camera.
I suggest the red suit is TYR Durafast:
