I for one would love to have something akin to my winter Carhartt gear with some cool woven scene on them instead of plain, boring, without-imagination black. I'd even be willing to pay a 10-20% premium for it and order it months before the seasons I'd be wearing it in.
The only real place you have cool customization like this still going on with any regularity is sneakers.
I'm not saying you did anything wrong. Just sharing why I think your comment was downvoted.
I think the problem is that you have a thing with no moat. Once you start getting any traction, you'll be hit by the drop-ship and print-on-demand guys who'll lemonize the market. You see this with 'Vaporwave' and 'retrowave' clothing which had a short Renaissance.
The opportunity is for the guys close to manufacturing who can rapidly print out each one and then spend the rest of their budget on marketing (say on Instagram).
Alternatively if you have a big brand, you can pull off stuff like Supreme's Dragon Work set (which I do have) but otherwise it's hard for people to spend because they'll assume they're buying from a fly by night print on demand Shopify site.
