Do any of you guys have your 8 oz suits double stitched or something? I had a fitting today and I'm concerned an overly deep squat could lead to some unfortunate consequences
Every tailor I have known runs two lines of stitching on the seat. One on top of the other. There is a special nylon thread that has a natural elasticity to it that is designed to use only on the inseam and waist/ seat seam. We use this on certain cloths.
What you are describing doesn't sound like a comfortably cut trouser
Depending on the tensile strength of the cloth, I would be concerned about the cloth tearing rather than the seam splitting.
