Yeah I love the jacket, managed to bag it from eBay just recently. Seriously nice, always regretted not getting it at the time.
The jeans are tailored, it's the only way to get that extreme skinny taper fit imo.
Never been into a proper Tailors before, where do you get them done and what do you ask for? Just to make them skinny? I've got a pair of 'Slimmy Chinos' that I'm looking to get done in the same manner, but I wouldn't have a clue what to say to them/I'm worried they'd screw it up.
Honestly, I broke down and bought myself a sewing machine a while back. Pretty much every shirt, pants, or jeans that I own needs to be slimmed and hemmed, so it's already paid for itself in tailoring costs. Simple tailoring and hems are easy to do. Anything difficult (suits, etc) I still take to the pros though.
There are tons of great YouTube videos to teach you the basics of what you want to do (ex: How to hem jeans). It's really easier than you might think!
