Q: How far in advance should I send social invitations?
A: Party or shower invitations should be sent one month before the event. Any sooner than that and they tend to get overlooked or forgotten about, and any closer to the date and people will likely already have plans.
Mailing them a month in advance means it’s a good idea to order them 2-4 weeks before then, to make sure you get them back and addressed in plenty of time.
