I've read Manton's proposed ban on hacking pockets, so was hoping to get some iGent groupthink support.
Other suggestions on styling also welcome.
Go ahead and get the hacking pockets. I don't care for them, but it's a subjective thing and works with your fabric especially if you have a 'country' thing in mind for the jacket. A "proposed ban" isn't the stupidest thing I've ever heard, but it's keeping fair company with it.
If I'm going to make any recommendation to you it would be to dump the idea of a ticket pocket with hacking pockets on your country style jacket. What do you have tickets to that you're going to ride your horse to? Not that there has to be a functional reason for an aesthetic feature, but the main reason people have been putting ticket pockets on their jackets is because it signals a bespoke make and gives the appearance of weath and priviledge. However, things have moved on over time and ticket pockets are taking on the look of an affectation of someone behind the curve. People of genuine weath and priviledge don't carry tickets in pockets, do they? They don't even have tickets. They're smuggled in the back door of whatever event/venue and wait in a VIP lounge for the whatever it is everyone else has tickets for, right? But if you like the look for your jacket, I'm not stopping you....
....or initiating a ban.
