Great ideas always start with a niche. Moreover, they almost always start out looking dumb.

and therefore, ideas that seem dumb and niche must be great

The example was of someone who is tall and doesn’t find clothes that fit them.

For the average consumer, clothes fit them.

There is no generalizability from a niche possible here, since the mass market is already served.

		Actually, I think you're really underestimating how many people struggle to find clothes that fit them well. Most people's bodies are not perfectly average. For clothes not to fit well, you don't need to be a significant outlier in one dimension. Just the accumulation of several smaller deviations from average can be enough to create an awkward fit. Beyond that, even if we limit it to height alone, there are hundreds of millions of people who are much shorter or much taller than average.

		I can assure you having observed the process of clothes shopping for the women in my life, that as far as they are concerned, clothes do not just “fit them”.
