To answer your question, I think it's fair to say it's personal preference. I tuck my shirt in when wearing a polo shirt but don't tuck when wearing a t-shirt. Then again, there are no rules.
And Rowdy Roddy Piper didn't actually wear it IN the ring, just on his way to and fro. I've also seen some postings about a tag team duo "The Highlanders" I believe they're called. (I haven't watched or followed any wrestling since I was a little boy.)

To answer your question, it's certainly a personal preference. I myself always tuck my shirt in, even if it's a t-shirt.
