As soon as I loked it I felt like a cage around my breast. Taking a long breath you feel it much more! And then the straps were falling down, so we reguleted more tight and there were pushing on my shoulders. Much more when raising arms.
I kept it for about ten minutes and when I removed it, it already left marks on my skin.
It's really unbelievable how much hard must be to keep it on all the day long! Poor you girls, I felt so sorry!
