PANTS PATTERN ADJUSTMENTS : FIXING CROTCH SMILE & FROWN LINES

If you have lines at the crotch you may need to lengthen or shorten the rise of your pants.

The direction of the lines, a smile or frown, will tell you whether you need to lengthen or shorten.

SMILE LINES (A):

PROBLEM: 

  • Tight diagonal drag lines at the front pointing out & up from the crotch.
  • The rise is too low/short.
  • This can happen because your rise is longer than what the pattern is drafted for.
  • Add length to the rise above the curve.
  • NOTE: These lines are similar to when a high hip adjustment is needed. BUT much shorter. Please check on the following page.

SOLUTION: Lengthen the rise.

 

FROWN LINES (B):

PROBLEM:

  • Frown lines on the front, radiating from the crotch.
  • On the back, there may also be horizontal lines below the waistband.
  • The rise is too long.
SOLUTION: Subtract length from the rise, above the curve.
