I've been to a lot of Cathedrals all over the world, and while one or two are unique, most of the time they are the same. This one is unique in how bright it is, and feels kinda squatly built. Bring some cash, about 100 per person, to get a ticket and audio tour available in several languages, and casually stroll through and listen to the history and see art that's been here over 500 years. They will evaluate if your clothing is modest enough (long enough, no visible shoulders) and provide coverings if you don't meet the standard.
