I am 6'3, 195 lbs. I wear an 8 or 10 in skirts and pants, but a 1x or 2x in tops, and a 14 or 15 in shoes. It makes finding a dress difficult, so I tend to favor separate tops and bottoms. As for the tops, I found a good tailor that will make any blouse mkre form fitting, since a 1x, while it fits in the arms and shoulders, would look like a circus tent, without some tailoring.
As for shoe height, I stick with a 1 1/2" or 2" inch heel, and then try to just own it.
