Perhaps you can help us answer this question by giving us a little more detail.

Semi-Formal is such a wide and poorly defined thing. Do you know what the other people will be wearing? What will the ladies be wearing is always a good indicator of the level of formality of an event.

The Prince Charlie Coatee is considered to be the kilt equivalent of the tuxedo. Or Black Tie if you will. If the others are not wearing a tux then the Prince Charlie would be overdressing for that event.

Perhaps another way to answer your question would be to direct you to our thread 1 kilt 10 looks. Two of our members used the exact same kilt and changed only the accessories to achieve 10 different levels of formality. Perhaps you can find some inspiration.

This thread may be found as the first 'sticky' thread in the General Kilt Talk section of the General Kilt Talk Forum.
