Dh's brother is getting married in Vietnam in May this year. Dh would like to wear his kilt (and new sil is also very keen) but he is worried that it will be ridiculously hot. It will be 25-30 C and humid. He has a wool kilt and a prince Charlie waistcoat and jacket. So will have 3 layers on top. He had thought about a ghille type shirt but he really doesn't like them. Anybody worn a kilt to a tropical wedding, any advice?
