Waist measuremenr

I watched your video on waist measurement

but still a little confused. When I measure, the tape cannot press into the sides of the abdomen at all, or it is ok if it presses a little? If it presses a little my waist is 34, if I just gently lay it on the sides of the abdomen without any pressing it is 35, so wondering how snug the tape should be around the abdomen for optimal measurement.

The tape should not compress the skin significantly. Definitely not enough to produce a 1" difference in measurements. This is one of the reasons a spring-loaded tape measure can be helpful, though a regular tailor’s tape is workable for sure.
