But generally, it's an odd jacket if:
- it has a very heavy and/or soft cloth, that would be hard to maintain a crease in trousers
- it has cloth of a very strong texture, e.g. a fluffy herringbone or a donegal tweed; there are such suits, but unusual, largely because, as above, the trousers won't keep any shape
- it has a very large or bold pattern; exceptions are found, especially as windowpanes are in vogue on all the style blogs, but you're still unlikely to see a gunclub check suit
Based on above markers, the following jacket might be an odd jacket: thicker, fuzzy fabric and windowpane pattern. I am still not entirely sure though (still strikes me as a possible orphan). I do however feel that, even if this might be an orphan, it is not too obvious and therefore can be worn as an odd jacket. Anyone care to chip in his 2 cents?
PS: Sorry for the repetitive questions on odd jackets. I still find it hard to see the difference on lots of occasions
