Sleeve fillers are items used to fill the space between a garment's sleeve and the arm. The two crossword solutions for this term are ARMS (4 letters) and LPS (3 letters). ARMS stands for 'Arm Sleeves' and LPS stands for 'Lace Puff Sleeves'. Arm sleeves are usually made of a stretchy material and are designed to fit snugly around the arm. Lace puff sleeves are typically made of lace and are designed to add volume to the sleeve. Both types of sleeve fillers are used to create a more flattering silhouette.
