We’re talking about an extra $100-$150 or so on a hat which will last longer than the cheaper ones, and is only a once every year and a half to three years’ purchase. It’s something which is worn (when new) on Shabbos and Yom Tov, so as a nicer looking item which in the long run may only be marginally more expensive (if at all), is a very reasonable expenditure l’kavod Shabbos V’yom Tov.
You make it sound like we’re talking about custom $1000 suits, $250 shirts and ties, and $400 shoes, or going to Prime Grill twice a week.
Gimme a break.
