Garment borders (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
hems
'garment borders' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hems that I've seen before include "Stitched garment edges for Shem" , "Stitched edges of cloth or garments" , "Stitched borders" , "Fringes" , "Bottom edges turned under and sewn" .)
