How to read drag lines
Drag lines (also called tension wrinkles or pull lines) always point toward the problem area — they radiate from where fabric is under the most tension. Understanding which direction they run tells you what's causing them.
Diagonal linespointing upward from the crotch typically mean the rise is too short for that piece (front or back). The fabric is being pulled upward because there isn't enough length to reach comfortably.
Horizontal linesbelow the waistband usually mean too much length — the fabric is folding because there's more than the body needs.
Smile lines (curves arcing upward under the seat) indicate the back crotch curve is too shallow — the fabric wants more room through the curve.
Fix one issue at a time. Start with rise (it affects everything else), then tackle the curve, then width.
