Six pairs of Land's End Chinos - Six different fits 😧

I recently purchased six pairs of Land's Chinos, all Tailored Fit, Flat Front. Every single pair of the pants fit differently. From 'darn I wish these were not falling down' to 'I can't breath'. Remarkably, they all fit my thin legs and butt pretty much the same with no notice of difference. I'm finding after wasting a bunch of money that the LE Tailored Fit have the rise and leg slimness I need. However, I'm struggling with the variation in waist size. Has anybody else experienced this?
