If your boyfriend or husband is going to wear a tuxedo to an event, and you want to get him a tuxedo vest, then here are some tips to help you decide which vest to buy.
1. Consider the event time that he will be attending. For daytime events, gray vest is the best.
2. For formal events, stay away from vests with bright colors or patterns. Unless the event is casual and somewhat a lighthearted occasion, then tuxedo vests with prints and images are fine.
3. If he is attending a formal evening event, then pick a vest, usually white or black, preferably with a pique collar.
4. If he is going to wear a jacket throughout the event, then a backless vest may make him look less bulky.
5. Does his weight change often? 
If yes, then consider getting him an adjustable full-back vest with adjustable straps to accommodate for weight changes.
6. It’s always good to have more than one vest for a man who has to attend events quite regularly. This allows him to look different even if he is wearing the same old tuxedo.
