Put it in a plastic case and wear it like a medallion.

You prompted me to go look - interesting that there are different sizes available per item (even between the tshirts). Wonder if some are sold out and they're just not showing?

Yes, some are available up to 2XL and 3XL, which tends to be enormous sizes in the US.

I would snark that 2xl and 3xl would be considered regular sizes in the US, and enormous sizes in the rest of the world.

Profattip Linus Tech tips clothing line has awesome fat people sizing and the stuff fits well too.

buy one and use it as a goal to fit into by X date?

I do have a “goal shirt” already… but maybe two would double my motivation?
