I think that ALL the Sons of Scotland, Ireland, Wales, and England who are in the adult online community should wear a kilt at this Internext. I will be wearing my clan's colours, so I won't be wearing a UtiliKilt, even though they are cool. I definitely think that there are a few besides Z and myself who have the stones to wear one.
IF you DON'T have one there are a number of places to get them, this is the one that I used to order a more lightweight version, and they do phenomenal work.

They have like 7,000 different tartans, and if you do the measurement process right, it will fit perfectly.
If you don't know what your family's Tartan is, you can look for a match in their database, and if you don't have a family tartan, it is completely cool to go with the standard "Black Watch" tartan (Scotsmen who are STILL some of the fiercest fighters in the British army).
Since the show is in FLA, I recommend going with the 8oz Tartan, because it is a lightweight fabric and won't make you sweat ... plus there is the aspect of the draftiness of a kilt (which is part of the reason they're so comfortable.
It's going to be a sight to see that is for sure! Cheers!!
