Here is a link to a Navy Mess Dress Jacket. It's 219.00. You would save about $100 on the price of a 100% wool PC or Argyl. It looks spendind with a kilt. Because of the higher waist of the kilt you will not need a cumberbund, but you should wear a belt. This jacket is for more formal occasions. If you want an excellent all around jacket, spend the extra for an Argyl.
White shirt with whichever collar suits you. Black bowtie is the norm but since it is the MC ball you might want to opt for a red one. Some MC officers as well as some of the Naval Officers that attend will wear a red one to honor the Corps.
If you are unable to aquire a jacket in time, wear a white long sleeve dress shirt (not a formal shirt w/ruffles) and bowtie. I'd opt for the red in that case.
