Yes, some of the apparel is expensive. $110 for a polo shirt is quite ridiculous, but people are going to pay it because it has a name on it.
Even super small startups are charging $60+ for polos and they're a new company whose stuff is made the same place as everyone else overseas.
It is what it is but yes, I think it's getting too expensive.
I was always untucked, but I got into the habit of playing with my shirt tucked in in the last couple of years because of being able to play a couple of private courses. There were no rules, it just seemed like the thing to do.
