I think everyone is extra careful with these measurements, I mean, no one wants a poorly fitting suit. From what I’ve gathered from local tailors and people on the forum, the problem with lanieri and companies like them, is that they adjust an existing size to your measurements, and if your body type is not very common, those adjustments don’t really work well. I will certainly try them on site next time, at least if the suit fits poorly they can see it right away.
