I have a semi-formal event coming up. I can't afford an Argyle jacket yet and I'm too busy to convert a sportcoat. So I picked up a cheap 5 button waistcoat. I shall be wearing my SWK black tartan, white shirt, tie and my new black waistcoat. Any other suggestions would be appreciated. My question is this with 5 button do I do them all up or do I leave top and bottom buttons undone? Can I leave them all undone?
Thank you.
