I recently moved out of the state I will be married in and am planning on iniviting my former co-workers. A few years back one of the coworkers, instead of sending out separate wedding invitations to each of us (it's only about a dozen people if that), just brought in 1 invitation to work for all of us and we verbally RSVP'd to her. I would prefer to mail the wedding invitations to each individual, but would it be tacky to send a save-the-date to the workplace?
