All of my suits are made to measure and it is absolutely worth it. For $400-$500 you have a garment that fits PERFECTLY, and that’s what makes it look good. A $100 jacket with $100 of tailoring will always look better than a $1000 off the rack.

It is however a skill and a profession so I would not recommend trying to make your own clothes unless you’re doing as a hobby rather than to have nice things.
