Does she have a good sense of 'laugh-at-myself' humor?
Do you know her well enough to make it a funny gift?
Has she been to many showers herself over the years?
Does she know that many showers bring gifts of lingerie, personal items, references to sexy things and having babies? She *may* be past some of those in her life now, but would she enjoy being reminded that a new bride - of any age - deserves those sweet reminders? I'm talking tasteful but definitely feminine.....not a long flannel gown, but maybe more than one guest could go in with you on a short cashmere robe, for instance, in a pretty, girly color. Or a collection of products in her favorite scent.
Otherwise, monogrammed items with her new initials.
Or a sterling frame for her wedding picture/s.
Or engraved address book to accommodate the addresses of both of their circles of family/friends.
