In November I will be taking my third vacation trip to London in four years. This time, unlike in the past, I will be attending a performance at one of the more elegant venues in the city: the Royal Opera House for a performance of the Royal Ballet. My ticket is in the amphitheater section (the top most tier). What is considered to be a man's "well dressed" outfit and a "minimally acceptable" outfit for this venue? My problem, as you can guess, is that clothing such as a suit or a sport jacket and slacks for a one time use will take up a lot of space in my luggage; I need that space for rain and cold weather gear since I will be outdoors much of the time.
Thanks for your input.
As a foot note, when I attended performances of the San Francisco Bay Ballet I would wear a jacket, tie, and slacks. I wear the same when I attend performances of the Pacific Northwest Ballet. However, I notice a lot of men wear shirts and jeans at the PNB which seems to be ok for Seattle. Can I get by with something like a dress shirt, tie, light sweater, and khaki trousers at the Royal Opera House? All of these items have a use outside of the Opera house unlike a suit or a sports jacket. These would be worn underneath a Barbour raincoat if the weather was bad.
