Depends on how formal you want to be..
A Dad would normally wear a suit and tie and Mom would wear a dress.
Hope this helps.
There is usually no ceremony but you are a HS grad since it's equivalent.
It depends on the season and how formal the school is, but dressing in professional but celebratory clothing is probably a safe bet for parents.
I think it depends on your parents. I would say about 3-4 inches
Yes, they do. A simple Google image search will reurn some pictures of them at a recent awards ceremony with their parents.
No,you dress the way you want to.
A distinguished professor should wear a conservative, yet elegant, go to a ceremony.
The parents
When my daughter, Kristen, graduated she wore comfortable pants and a shirt under her grad gown. Some of her classmates wore dresses and others wore shorts! There is no rule for what you must wear under your graduation robes! Let your plans for the day dictate what your "under grad gown" outfit will be. You, of course, want to be comfortable, so choose an outfit that's not too big, bulky or hot. Your graduation ceremony could last quite a while so you want to make sure your not in a very hot or ill fitting outfit. That will make the graduation seem even longer! If you are going to a party right after your graduation ceremony, what kind of party is it? Formal or informal? You will want to dress in an appropriate fashion. Bottom line is dress how you feel comfortable, but make sure your outfit isn't too sloppy. This is your graduation...you want to look your best!
Help me!
Not entirely sure what grad nite is but if you're worried about it, wear solid plugs. They look more like studs than tunnels or tapers.
Is it okay to have a small ceremony and not invite my our parents spouses?
in a Japanese tea ceremony men usually wear traditional kimonos with a hakama or formal dress tied around the waist they also have washi paper tucked in at the kimonos collar when they revive sweets in the ceremony this acts as a plate.
