If you have a creative note to you, a bit of persistence and dexterity, one of the best ways for you to be sure that you’ll always be able to have any kind of clothing item that you want without having to pay almost anything for it (you’ll always need to spring for the material) is to get proficient in making your own clothes.
While this is not something that everyone will master, and even though it will require an initial investment for the sewing machine, other equipment and materials, those who are skillful enough can easily copy any item of clothing that they see at a fraction of the cost.
The most important tool that you’ll have to rely on if you plan on doing this is the sewing machine. It is also the most expensive piece of equipment that you’ll have to buy. Basically, when it comes to sewing machines you have two types, industrial and household. Both have their advantages and disadvantages, and the choice you make will usually be based on personal preferences. Industrial machines are bulkier and you can’t exactly move them around the house, but they are more powerful and able to be used for sewing difficult materials. On the other side, household machines, even though they are generally weaker, are more versatile, as they are usually capable of doing different types of stitches, while the industrial ones are limited to one type of stitching.
Regardless on the type that you choose, you’ll need a lot of practice before you are able to use it proficiently enough, which is why your first few items of clothing should be something really simple and made from inexpensive material.
