Fly... Correct way to put it on, as so many do not appear wearing this correctly

[CollinMacD]

I have a fly that I think I have worn correctly in the pas, but want to makes sure I am wearing it correctly for this upcoming event. You-Tube, watched several videos, but I am not convinced on they way it is worn. When you put the broach on do you go through the fly and your jacket? Wouldn't the pulling elongate the pin holes, stretching out the jacket and fly material, making a visible pin hole.

Are there any restrictions or concerns about the broach pin itself, when going to a formal affair? Anything that would be considered incorrect or casual?

The reason I ask, I have a formal tartan ball in a few weeks to attend, and I want to wear a fly, as most are wearing them. In doing so, I want to make sure it is worn correctly.

Any advise is appreciated. I hate to be incorrect or not wearing attire correctly, I just want to make sure about the traditions and proper wearing of the accessories.

Also, at a Military Ball, white cotton gloves worn by men are normal, at a formal tartan ball, are white gloves worn by men normal or not?

This is our first formal Tartan Ball, been to many Burn's Night Out, but being held in the Willard Hotel, Washington DC, I am sure there are protocols and proper clothing standards that apply, well I would hope there are, but in today's world of casual dress all the time, seems like formal is a lousily used world, with a much more slack definition that what I remember. Working in Embassies overseas, formal meant formal, but in the civilian world, I am sure it is much different. Just would like some advise from those who have attended these affairs in the past.

Thank you,
