It's highly subjective, but...
The most common temperament is SJ. Assuming all SJs share a similar taste in clothes (they probably don't), if they consider themselves stylish, then they probably also consider the other SJs stylish. This would mean that almost 50% of the population (SJ) likes approximately the same type of clothing (the other 50% is composed of NFs, SPs and NTs, all different temperaments, so more likely to disagree with each other). If the definition of something is what the majority thinks it is, because screw dictionaries, and the majority are SJs, then style = what SJs think it is. The SJs think they are stylish because now we're also assuming that most of them have a healthy self-esteem. SJs are stylish.

So, the winner is/are...
ESFJ, or ISFJ, because they actually care.
