Trouble with Fashion

Tonight,I'm invited to a dine-out with people from Australia. They are family by marriage through my second oldest brother. It is a formal occasion, so the dressware must not be of casual t-shirts, which I am mostly dependent upon for everyday wear. Now, Im facing a problem I have not yet accustoedto doing. I don't usually wear the formal clothing. Shirt, tie, suit, not my appetine. However, I have to for tonight. First time for everything, aye.
