I mean, you do you.
Clothing is really _fashion_ for tons of people. Fashion is art. People like art.
Yes, I am one of the people who has a preferred tailor who can do more than just let trousers waists out. I also know where the nearest cobbler is. That’s not normal, though.
A dead industry often doesn’t entirely disappear, it just shrinks a bunch and comes to rely entirely on enthusiasts or very rare actual need, rather than broad need or appeal. Consider the draft horse breeder, or the carriage driver. There’s a market for both professions! But they’re itty-bitty. The day-to-day need for both is gone.
Tailoring is hovering right in the edge of that kind of status, today. It’s dying, killed by $10-30 shirts and $20-50 trousers and $50-100 jackets all from largely synthetic materials, and a society that no longer expects anyone to wear anything “fancier” outside certain events.
I mean, outside very unusual circles, dinner jackets are essentially ceremonial costume-wear, and business suits aren’t far behind on that track. You gonna wear a tailored wool hacking jacket or breathable linen Norfolk suit on your camping trip, or a bunch of polyester and nylon stuff from REI? LOL. All the situational tailored clothing but the business suit and blazer are near-extinct unless you want to look like a cosplayer, and those are on borrowed time.
As someone who has tried to make several businesses around art, people generally like art but not enough to pay "at scale" money for it.
