Informal Wedding Attire Advice Needed.

[Sir Robert]

The real killer can be the weather, it can be hot and humid by late May so the tie and jacket might be out reguardless just because of the heat. I will have a jacket, shirt and tie ready but I could be forced into a poet's shirt.

I want to aim at nice day wear if the weather permits.

A nice bonnet will be worn (Beret looking thingies).

If you haven't seen it yet, take at look at the guide @Nathan and I put together: traditional-highland-civilian-dress-definition-guide-visual-examples. In the first set of pictures, you'll find several options for warm weather attire that don't involve a poet's shirt. There's no need to be "forced" into it!

If you really like the poet's shirt (aka a "Jacobite" shirt), then suit yourself—as long as the bride and groom approve, of course! Be aware, however, that such an item is anachronistic and many people (myself include) consider it to be a costume accessory...

I seem to be living in an alternate reality. The standard shirt and tie have been around since the 1800s, I can not see them as anything other than an anachronism. The poet's shirt is (to me) more like a classic that has never gone out of style in 2000 years. Let's face it the kilt is Victorian fashion.

Sir Robert,

One child being married is stress enough. But two children getting married close together. My suggestion is to tell both of them to elope. Send you postcards from their honeymoon destinations. You save money and do not have to worry about what is too formal. LOL (When I was a teen, my ex fiance was one of four daughters. Their dad offered each of them $2,000.00 a piece to elope. He figured that he would still come out ahead on stress and money. Unfortunately, he died before any of them were married.)

Good luck to you and your family as you share their happiness.

The problem with the so-called poet's shirt or Jacobite shirt is that as I've been informed, historically, it really is neither. It is a more modern concoction that is designed to create the impression of something. It is not contemporary to the genesis of the kilt.

Sir Robert, imagine being inside the brain of either of your daughter two days before the wedding. Now step back and look at yourself. With none of their anxiety, I think you'll be fine with your choice.
I do like the "take the money and run" advice, but I have no daughters.
