I picked up one of the Burnett's and Struth casual kilts in ancient MacKay (I'd ordered weathered Ulster only to find out they were out of stock). It is a surprisingly solid little kilt for the price. My only objection is that the reversed pleats under the aprons are a wee bit scanty---but I like quite deep reversed pleats. I like this kilt quite a bit.

If you're going to go for a synthetic kilt, my advice would be to go with good Marton Mills poly-viscose. I've got several kilts from USAK made from the Marton PV, and they're dang near bullet-proof. They have the look of wool, and are very comfortable. While Rocky (at USAK) generally divides the choices up between the five yard casual (with pleats fully sewn down) and the eight yard semi-traditional, he made my US Army tartan kilt up as a "five yard semi-trad." He might be amenable to doing up a five yard semi-traditional for others, as well, which would reduce costs.

Both the Burnett's and USAKs are custom tailored, and that's a good thing. Even if you've got an "off the peg" body, tailored garments have a special charm, fit and appeal.

I've never owned a Frugal Kilt, but I've had some SWKs. My main objection to the SWKs is that they seem hotter to me than my other kilts. The acrylic looks good and swishes well, but just seems to build up heat more than wool and PV. Also, the SWK heavyweight doesn't have the pleats cut out at the fell, giving a "pillow butt" look, and also making the kilt wear hotter than most other sixteen ounce, eight yard kilts. With that said, however, Jerry at SWK offers lightning fast shipping, good pricing, and the kilts are "solid beaters."

I think any of the options outlined in these responses would work well and look good at your wedding. (Congratulations, by the way!) I would probably orient my choice based on the best man. Is he likely to wear the kilt out and about in the future? Will this be a "one off" event for him? The more likely he is to wear a kilt in the future, the more likely I would be to invest in a USAK or Burnett's and Struth tailored kilt.

I hope this helps, and once more, congratulations.
