My husband's son is getting married in October, his first wedding, his fiance's third wedding. The invitation did not specify formal wedding, but we were informed my husband must wear a tux, no mention of what I am suppose to wear. The wedding will be at 7p.m. on a Saturday with reception to follow at a small country church. My husband feels awkward about a formal wedding, since the bride has been married twice and the couple have two children already. Should we go along and do whatever requested? The couple has requested that I not sit up front with my husband, since I amnot the biological mother of the groom. I find the plannign very strange.
You should be sitting with your husband in the third row. If the biological mother doesn't mind, both of you could sit with her in the first row. Splitting you up is not proper or polite.
If you are not being treated as one of the mothers, which it appears the case, you would dress as one of the guests, even if your husband dresses in a tux.
The tux and formality is fine even for the encore wedding.
