Bought another RLBL suit in navy blue and this morning when I wore it and moved my arm to reach something I heard thread popping sound from my armpit area. Is this because it is a new suit? I have the same size suit in black and never heard thread popping sound. I took a bright light and inspected the area but didn't see anything that had come loose. My tailor says bring it in and see what the problem is. Anyone have any idea?
