I am planning my friend's bridal shower and we are inviting a bunch of friends from her work. She doesn't have their home addresses so we are sending the invites to work. My question is do we send an individual invite to each person? I know for wedding invites everyone over 18 gets their own invite but it seems wired to send 13 invites to her work. However, it also seems wired to put 13 names on an invitation. I could use some input/advice.
