I'm going to sound weird here but to me, a person that isn't really all into designers and brands but looks at the article of clothing itself mostly, the items that Meghan wore on the tour that stood out for me were the ones that made a difference.
The Outland jeans (which a report says she wore 6 times) gave a boost to the women in Cambodia that make the jeans to avoid poverty. She wore Veja shoes that were made from plastic bottles and other materials. Seeing those, I bet she felt Charles smile from oceans away. Then there's the unique piece of macaroni jewelry which skyrocketed Gavin to international fame and boosted his work for a stillborn children cause.
What Meghan wears *does* matter and its seeing the impact of these items I've mentioned that has cemented an opinion for me that Meghan *would* be wise to up her game with British made clothing. When people pay attention to even the smallest detail, the smallest details need paying attention to.
As far as the DF goes, know what I'd like to see? Someone actually writing an article on Meghan's clothing but along with listing the price paid for an item (say Outland jeans for example), do a bit of research and figure out just how much revenue the Outland women brought in because she wore the jeans. Like her joint effort for the cookbook, her initiative with the project skyrocketed the sale of that cookbook and benefited the Hubb Kitchen immensely. Could the DF do a check and balance article? I doubt it. They'd have to do actual research.
