As for how I relate tasteful and elegance to Ni, I didn't conduct the study. However, it does seem correct. consider the ENTJ versus the ESTJ. The ESTJ dresses appropriately, according to social norms, and for functionality. The ENTJ, on the other hand, definitely dresses more tastefully and even elegantly than the ESTJ. There is an individual flair to the ENTJ's manner of dress.
