SF surely gets all worked up about grey odd jackets, and I don't see why, they're honestly not that hard to pull off in real life. Sure, a navy jacket might be easier, but sometimes people want some variety in their wardrobe. It would be really boring if we'd all be wearing navy odd jackets with mid grey trousers.
Unfair statement. I'm not advocating for blue OJs, I'm advocating against gray OJs that looks like orphans. Stiches's gray OJ has a shade of gray that has proved to be a bad choice, a dark gray (the acclaimed Harris Tweed herringbone, for example) or light gray would be much more easy to pair, specially if there's texture interest.
