The primary purpose of the subscription is to pay for the care of the hounds, and to maintain things like coops and gates that might be placed (with landowner permission) on private land to facilitate access. The kennel needs to be kept spotless, needs to be repaired, usually has a septic system, electricity bills, etc. Just image putting Frontline on a kennel full of hunting dogs each month. Paying the huntsman’s salary, including health benefits.
So - you really need to learn about hunting before making a bunch of snap judgments. The subscription is used to pay for things so you can hunt.
Do the clothes make sense? Of course they do. And you wouldn’t wear white breeches, and the clothes are just the attire for that sport. The attire means something, and it is truly functional.
Exceptions are made for certain climates and local custom - but foxhunting isn’t trail riding. You’re hunting. There is an established order to it and a hierarchy - mostly for safety reasons. What you dismiss as old fashioned - you know - some of that stuff is superior than most anything on the market today.
It’s not a glorified trail ride. Foxhunting is dangerous and people get killed or severely injured. Horses can be injured or killed, too.
It’s a great sport. But it’s not for the faint of heart. Hunts have slower groups and some hunts allow western riders or have more relaxed rules for various reasons. If you’d like to try it, I suggest you not come out with that attitude. You won’t be welcome if the first thing out of your mouth is how idiotic everyone looks.
And truly - a hunt club is expensive to run. The huntsman is a professional, and he’s paid. The hounds have to eat, they need shots, they need good care. They need decent housing. It’s non negotiable - the welfare of the hounds comes first. That costs money.
That’s not snobbery - it’s just a fact.
ETA - for the record - I ride to hunt. Not to show off my fancy clothes. I’m correctly turned out for very little money and that silly old fashioned idiotic 4 fold stock tie has been used several times to bind up injured people. My silly old fashioned wire cutters in their silly case have been used to free a horse hung up in old barbed wire, and to free a hound whose head was stuck in a hog panel. Both hidden dangers in my territory - as it’s very overgrown and trappy.
