Yes I always give my married sims a ring. For women I usually give them the one with the big diamond (the one that the proposal animation uses) and for me I give them the plain band that goes on the ring finger.
Maybe it's trait based. The groom's traits are bro, playful and erratic and the bride's traits are neat, clumsy and foodie. It's weird though because the bride was the one who did it and she has the neat trait while he has the playful trait

Oh right sorry, when I try to decorate the seasons Christmas tree with ornaments they don't show up after my sims finish it but all the other types of decorating options work.
