St. John Slate Blue Pants Heavyweight Womens Size 10 Flaw?

FLAW? I don’t know if this is common for these pants or not, so I am disclosing it regardless. On at least two of the seams inside you can see “banding” underneath. These are very heavyweight and warm. Unknown fabric content. Size 10 Measurements Waist 15 inches Inseam 25 1/2 inches Length 36 1/2 inches We are a dog friendly home.
