Post to r/memes by u/McTavishSoap, only text in message reads "Legend of Zelda". Image below it contains two image, first image reads "Girl's pockets" with a picture of a pocket small enough to fit an index finger in next to it. Second image reads "Boy's pockets" with an inventory screen from Legend of Zelda right next to it.
Doesn't tailoring services already exist?
Yeah, they do, but theu're not as readily available as one would think. They also don't advertise this possibility, if they even take such jobs (Many don't like to take on your standard wallmart jeans etc. for one reason or another). On top of that, I'd imagine that they'd take surprisingly large sums from such "extraordinarily custom modifications".
What I'm proposing is specializing your sidehustle to this "one trick pony", that is basically just making people realize that fake pokets can be turned in to a real pocket. This would provide a seamsperson quick small jobs as long as fake pockets are being made. And judging by the fashion industry, it will be a long time before they realize that those pockets don't need to be fake.
This is more of "call to arms" to "fight the power".
