2016/12/06 Dress codes for a wedding party

I was invited to a wedding ceremony and a wedding party afterwards. They are to take place next week.

I know that I am supposed to wear formal clothes at the ceremony, a black suit with silver and silk tie and a handkerchief in the chest pocket, which is also silver and silk. But is it the right clothing for the wedding party? It seems that the dress codes for a ceremony and those for a party are quite different. You should be dressed more casual for the latter, maybe. 

But as the party was to be held in Tochigi, I have no time nor intention to change clothes completely. So, I want to change ties and handkerchieves.
