Realized I didn't actually explain the measurement process. You put the phone down by leaning against a wall (or chair or something else), stand ~10 feet away (so your whole body is in frame) and do 1 spin. The software takes care of the rest. The app walks you through in much more detail how to do it. You also need to be in contour fitting clothing, so it's recommended to be at home.
Any reason to have it that way rather than shirtless? (My guess is that shirtless would be more accurate, but that you guys decided the privacy tradeoff was not worth it for the minimal accuracy gain.)
When you do it in the app, it does say that shirtless and briefs or boxer briefs are OK. I assume that fully nude would also be OK, but I guess they didn't want to go there. ;)
