Making your own clothing doesnt usually end up being any cheaper than buying it pre made but you can choose your own materials and tailor the fit yourself.

Its definitely a time thing though but modern sewing machines can cut down on it quite a bit.

Well, it depends on how you look at the price. Take the corduroy suit, for example. It took 4 meters of material. If I recall correctly, it was about €20/meter, plus the lining for another €40, so €120 in total. Then buttons, thread, and what not, MAYBE €20. I already own all the sewing equipment, so that's not really a factor after multiple years, but let's call that €60. Let's say €200 all in. Then it takes about 12 hours for measuring, cutting, and sewing.

A similar "fast fashion" suit is around €250-300, then it needs to be tailored, so let's say €350-400. I know what I'm about, so the quality of the handmade suit is better, with more precise and actually finished stitching, properly sewn on buttons, and much higher quality materials. It'll last for years with proper care, while fast fashion clothing tends to fall apart quite quickly.

So it's a bit cheaper in materials, a huge investment in time, but it fits perfectly and lasts much longer. Also no sweat shops.
