So in my urban fantasy story, among other things, new fantasy races suddenly start appearing in the modern world via the system I outlined in this thread:
Long story short, for a variety of reasons, a bunch of humans have now willingly transformed into a new species, and this happens about half a dozen times over the course of two or so years. Now a few of these have features which would require specially modified clothing to fit them (different foot shapes, multiple arms, weird ears that things like sunglasses don't quite fit on), and I've been operating under the assumption that the opportunistic and profit-hungry industries of the world would be racing to put products on the market to cater to them. But it occurs to me that I don't have a good concept of how fast that would be.
How long should I show these trans-species characters making due with homemade solutions before the free market starts marketing more professional clothes and accessories to accommodate their biology? What about the next times this happens? How much faster would the industry react to the next time a bunch of people suddenly decide to shapeshift into new creatures?
Edit: Just to give a clearer picture of the market share and profit opportunities, the current idea is that each of the first two transformations are taken by roughly 10-15% of the population (at least in America, where the story's set), while the remaining four get fewer takers at around 5% of the population each due to the changes being more extreme. By the end of year 2, humans will be 60-50% of the total population.
