Both women in groom suits and men in wedding dresses are inconsistently tagged - wife_and_wife groom and wife_and_wife suit -groom have similar post counts (4 and 5 pages), and so do male_focus bride and male_focus wedding_dress -bride (3 and 4 pages). I realize those are imperfect searches, but they should be fine as examples.
We should decide how to use them, and add it to the wikis.
