It's one thing when, as I was, you are stranded with an odd dinner jacket (velvet or Black Watch, say) that has grosgrain lapels, and you only have your trusty satin-striped trousers. It's quite another when you have purchased what purports to be a dinner suit that doesn't match those key features.
See if you can catch the replacement trousers before they are dispatched and demand grosgrain stripes, as was suggested above, or send the whole mess back and start over.
