I agree with Grant, if you might be more comfortable wearing your knickers, then do so.. if you want to go "regimental" that's your business. Things were done in the past, because of the age...long shirts were used to cover ones parts, and these days the shirts are not made the same...

I personally wear my skivvies, but wear black and always avoid answering the question, because it's noones business but my own...lol besides you can flash a bit of leg, and still keep them guessing..lol
