Yeah, thanks so much for having me.

So great to be here.

You just have to hold on to them for 20 years and then they'll be back.

That is, we found in the data that we analyzed that the period is 20 years.

And what was really exciting to us about this is apparently this has been known in the fashion industry for some time, but it's never been proven.

And then when we found it, we were mathematicians.

We looked at the data.

We found this 20-year cycle.

And six months after that, we realized that people had known this in the fashion industry for a long time.

Yeah, totally.

Although I've also heard that the early 2000s are back right now.

So the low waist jeans have been coming back, for example, which would be about 20 years.

Some people think that this 20 year cycle might be a generational gap.

So exactly what you're saying, maybe your parents are uncool or the generation right before you is not cool.

But if it gets old enough and it becomes vintage.

Well, that's a really good question.

When we first set out to do this, we started to think, okay, how do we even quantify fashion?

What does that even mean?

And we're mathematicians, so we like to simple things, make things as simple as possible.

We originally thought of something along one dimension.
