A black-tie dress code means you’re asking your guests to dress to a particular level of formality. Choosing a tuxedo for yourself doesn’t automatically mean every guest must do the same.

Think about the whole wedding rather than rules. Your venue, flowers, styling, time of year and overall level of formality can all help determine whether a tuxedo feels completely at home.
