Yukarin's average skirt length gets shorter every year

I said that aloud when I flipped my calendar today to see this May/June 2010 page.

Since I was thinking about it anyway, I decided to go back through some old concerts to take a look. Results...







There is clearly a trend as the hemline begins creeping above knee length. But of course we must be objective observers. Before we draw conclusions, how do we know it's not just random or if Yukarin is merely representing an overall larger trend? Well we'd have to compare it to a benchmark. Unfortunately, with my weak Google-fu I could not find year-over-year average skirt length data in Japan. So I used the next best thing. Normalized Nikkei 225 prices pulled for all of the concert dates. Why substitute a Japanese equities index? For the sake of this post, let's just make the completely ridiculous assumption that Hemline theory holds and that whatever tracks this mythical hemline has a beta of one.

So with that, if we consider the index to be reliable, it can be shown conclusively that KTS (knee-to-skirt) spreads on Yukari have been widening drastically since 2006. We can only conclude Yukari is clearly diverging from the trend with skirt length reductions which cannot be explained by overall shifts in the skirt fashion trends. Thus there is a strong possibility these changes are intentional and will continue further.

So... with Princess a la mode about to ship in a month, do we have to prepare for nosebleed levels?
