Ralph Lauren made a strategic mistake which has cost him some goodwill, and the shame of it is that they squandered a crapload of potential to capitalize on a trend that has passed the early adopter stage and into the mainstream. There are some very well known mid-tier American manufacturers who could have made the uniforms that Ralph designed. Southwick comes immediately to mind. "Ralph Lauren works with American manufacturers to make the US Olympic Uniforms" would have been a very compelling storyline. I know that RL does not have the same marketing strategy as J.Crew, but there's not shame to taking a page from a competitor's playbook, especially when you have such a unique opportunity.
Sadly there would be no story if they did go with US manufacturer's from the start.
