Yes, well-spotted, you two. Not by that much, but enough to change the balance a little. IRL, you really don't notice, but of course with a robo-pose, you do. I guess I could have the flaps of the pockets removed, which would draw less attention to the shortening - actually just tucking them in does the trick.
This is a general problem for me right now. I am gradually converting to having everything made bespoke but it takes time and money (or if you don't want it to take time, you have to have a lot more money). So in the meantime, rather than waste that money I need to save for bespoke, I buy the occasional second-hand pieces in decent fabrics that have a good general overall fit, and with some alterations will do for now, even if they are not perfect. That's life.
I totally understand. Length is just the toughest dimension to alter. I had a couple of jackets shortened, and I think it just doesn't work out well. Maybe you can take half an inch, but much more and you get the balance issues. I've come to accept that I must pass on these, no matter how well it fits in other dimensions or how desirable the fabric and construction.
