This is the most basic part of NBE but still I want to ask, what's the correct way to do it? I've always pulled the measuring tape right at nipple height, across the shoulder blades since that's how the method is described in online bra fitting guides. In September I went to a specialized store to get a bra fitting and there they used the tape pretty loosely, it was loose below my shoulder blades.
After that I made sure to emulate the way they measured me and the size apparently seemed smaller after that (I used to measure 80cm when pulling the tape across my shoulder blades and then it showed 77cm when it was loose.) I started NBE while I was measuring loosely but the last 3 days I started pulling the tape right across again.
So what's the right way to do it? Should I measure snugly or loosely?
