The plus size striped dropped-shoulder sweater lists a 14.4 in sleeve at 0XL and 15.6 in at 3XL. Those figures look short in isolation, but the shoulder spans 26.1 to 29.6 in across the same rows. A dropped seam changes where a sleeve begins; check the path from neck to cuff before judging arm coverage.

Use an existing sweater as a map

Lay flat a sweater whose cuff lands where you want it. Mark the center back neck, outer shoulder seam and cuff. Record neck-to-seam and seam-to-cuff separately. Ask the seller whether its shoulder number is measured across both shoulders and where sleeve length begins. Do not add half the shoulder figure to the sleeve as a promised arm length: the chart has not defined either origin.

Compare the four rows

0XL gives length/bust/shoulder/sleeve 24/47.6/26.1/14.4 in; 1XL 25/49.9/27.3/14.8; 2XL 25.5/52.3/28.5/15.2; 3XL 26.1/54.6/29.6/15.6. The bust grows 7 in from first to last row while the standalone sleeve number grows only 1.2 in. Check bust room on the reference sweater and cuff reach separately. Ask whether the bust is a finished circumference and request a cuff width if you need it over another layer.

Choose fabric and color on confirmed facts

The source lists 100% polyester, a ribbed finish and “highly stretchy,” without a stretch range or recovery measurement. Sand, Blush Pink and Light Gray are selectable. Compare the selected color against current images; do not infer identical fabric behavior from the generic stretch label.
