I recently purchased a 2 button black tuxedo for my wedding. While I can purchase the matching vest, I don't like how high (5 buttons) it sits on the chest. Ideally, I would like 2 studs to show with the vest on. While I know it would be a cardinal sin to get a different wool fabric vest to accompany my tuxedo, I was wondering if one could wear a vest that is mostly/all satin (silk?) so that there's no wool mismatch. Are these "universal" black formal vests acceptable? If yes, I would greatly appreciate links to vests that meet my needs. Thanks folks!
