Actually it sounds rather interesting
Indeed, it does, as long as they do not give short shrift to the human peacock, the male.
Going beyond the topic of medieval underwear, while I cannot say much about human fashion in this century, as we are less than a decade into it, last century, the 20th was--for me--one of the worst centuries, if not the worst century, for male fashion in the past 1000 years. On the other hand, the previous century, the 19th was--again for me--one of the best centuries, if not the best century, for male fashion in the pass 1000 years. Male fashion in medieval times, excluding underwear, falls somewhere between these two extremes.
Unfortunately, I won't be able to attend.
