Considering that you don't want a slim cut suit, and you mention that you're tall, so I assume you're a lanky build. Considering that, I would not go with a pinstripe, as that will elongate you further. If I were you, I would do a charcoal solid, or a subtle charcoal windowpane with medium to large squares.
As for the suits, assuming you're not doing MTM or Bespoke, you need a long coat. I actually don't know what european brands have extra-tall sizes, but I would look into those first. If those are not available, I believe that the longest cut jackets come from Isaia, Belvest & Corneliani, who cut a long to be right around 34" from bottom of the collar (I'm not sure if every silhouette is this way, but the ones I've seen were this long). If you can afford it (and if you have a strong shoulder), I would recommend an Isaia, as I think they have a great silhouette with the right amount of waist suppression, and their shoulders tend to be narrow. If you have more sloping shoulders, I think Cornelianis have more padding, and if you're thin and around 2m, it may be cut too loosely for your frame.
Of course, the best thing to do is to go and try out various things, but I think that's a good jumping off point.
