Some ideal garments, the most useful ones tbh, are not very difficult to make.
In fact, someone with a vague memory of sewing pillows in Home Economics several decades ago is more than prepared to break out the sewing machine
and stitch up a few skirts and even pants. Being able to make a garment is much the same as being able to make an omelet or a tomato sauce or a sandwich.
It is not difficult, but you do have to know how to do it, and be willing to take the time to do it, and to clean up afterward.
It does take longer than making a sandwich, more like making a nice dinner,
but it will still take less time than a grim hunt for a particular thing in the shops and malls of america,
which in any case will not end in you having an ideal garment.
Plus, once the garment is made, unlike dinner, you really do not need to make another one for many years.
And that is only for the garments you wear all the time and eventually wear out. Coats and robes might last forever.
