While buying purely local/domestic will reduce your selection somewhat, the majority of what you cut yourself off from buying are low-quality products anyway.

I don't think it's possible to buy purely local/domestic for everything, but for some types of products, the switch is relatively simple and something more people should consider.

One area that I have managed to go fully local in is clothing. Since I live in Denmark, I consider the EU+Norway+Switzerland to be "local", There is such a good selection of all types of clothes produced here, from work wear to casual wear to office wear and especially as you go into higher-end clothing, quality suits and of course anything tailor-made can be ordered made from locally-produced fabrics.

Yes, each individual piece will cost more than an equivalent from a fast fashion brand, but the quality will be on a completely different level. And obviously some raw materials can only feasibly be produced outside your local area, which makes some transport necessary. But I prefer raw materials to be transported relatively directly and unprocessed, so the potentially harmful processing be done in countries with strict regulations on emissions and harmful chemicals, as well as reasonable labor protections.

Unfortunately, as long as people look at price as the primary (or only) factor influencing their purchases, we're stuck with shipping clothing halfway around the globe for no good reason.
