In that post, your response to the risks section is that "there is literally no chance we're going to fail at delivering incredibly crafted shirts to all our backers." That is so completely disconnected from the world of reality that it shows a tremendous lack of foresight. Read literally any prospectus for companies much more proven and stable than yours and you'll see a litany of legitimate risks surrounding the business. Yours is no different. As a company who has, by definition, never done this before, your risks are quite high.

What if the fabric from your supplier is inconsistent in quality, do you have another supplier? What if your estimates are off, and labor+fabric costs more than $8, will your margins allow you to deliver? What if every other large manufacturer has discovered that the cheaper labor available overseas more than offsets the increased shipping costs? What if your manufacturer has a work stoppage, do you have another manufacturer you can turn to of high quality? What if their factory burns down? What if their quality is inconsistent? What if they don't deliver finished goods on time? What if your fabric gets damaged en route, do you have insurance?

I know next to nothing about clothing manufacturing, and I just listed more risks than you did. The risks section is not intended to be an exercise in braggadocio.
