DEAR ABBY: Is it proper to invite men to a bridal shower? -- CURIOUS GUY IN MINNESOTA
DEAR CURIOUS GUY: According to Emily Post: "Today, showers are just as likely to include the groom and his male friends."
There's nothing improper about asking men to participate. The purpose of a shower for a bridal couple (or the expected arrival of a baby) is to celebrate the upcoming event and express good wishes. It's also a way to give the couple things they'll need.
