Steaming/fogging is only an issue if you're using poor quality anti fog.
about £15 will buy you a tiny bottle of decent antifog, any less and it WILL be shite.
In all honesty you should just rent first, you might buy stuff you don't like or see something someone else has that you like, which you can buy because you're only renting.
Also think about where you're going to play. inside you might want a face mask and goggles with all flesh covered.
I was playing outside today, I had glasses, shorts and t shirt, but I saw so many new guys with helmet, goggles, mask, scarf etc who were just dying from the heat and not even enjoying it.
TL;DR - rent first. comfort And practicality come before looking cool
