Tucks in clothing (6)

Ross

I believe the answer is:

pleats

(Other definitions for pleats that I've seen before include "Folds sewn or pressed into cloth" , "Folds in garments held by stitching" , "As before, twists" , "Staple for cloth folds" , "Double folds in garments" .)

I've seen this clue in The Guardian.
