Military garb is pretty unflattering for people who are not the correct military size. If you look round, the uniform will make you look like a pig in the blanket or a puffer fish.

Secondly, borrowing only some of the military kit makes the civilian look even more out of place. Remember picture of Jarad Kushner wearing a flak jacket over a suit? It is like Ron Desantis wearing white boots in a disaster zone. It is clear that everyone else is going to get their hands dirty.
