At first...a warm welcome and congrats with your 1st kilt! (what tartan?)

Wearing black speedos or briefs is perfect!

You said it yourself...the black is good camo and because they're short...nobody will see what you're wearing underneath.

About kilt tipping (or a "kilt check" with a cell phone camera) just don't let it happen. When people ask about what you wear underneath just say it's none of their business.

Women love kilts and some get slightly overheated...you'll find out

Never lift your kilt...don't flash...it's vulgar, not funny and disrespectful towards the kilt. Tell this to your kilted friends also...a kilt is not a "funny party outfit to score a date". Besides...when you wear a kilt there's no need to act like a clown...people will notice you anyway.

Wear your kilts with pride and all will be fine.
