Hello, I can only afford to take lessons right now from studio A which is a legit school with a brown belt instructor who is not world class, but very talented. Let's say down the line I get my blue, and can finally afford studio B, which is a famous school with a world class instructor. At this point, would I wear a blue belt to the new school? What's the custom there? When I'm a purple belt, am I a legit instructor B purple, or is it misleading to say that? Would it be an insult to the original instructor? Does who taught you up to blue matter? I'm not belt obsessive, but if the time spent at studio A is going to cause headaches when i can afford to go to studio B, I rather just borrow some money out of my 401k and start the lessons at studio B.
