The A Note of Thanks cable-knit sweater has a round neckline, drop shoulder and ribbed hem. Its S–3XL chart includes chest and length, but the step from XL to 2XL is unusual enough to inspect before choosing between those two sizes.

Notice the width break

The XL row says chest 46 inches and length 23 inches. The 2XL row says chest 52 inches and length 23 inches. Moving up that single labeled size adds 6 inches to the listed chest while adding no listed length. The next 3XL row moves to chest 54 inches, still at length 23. If your current sweater needs more room across the chest but already lands at the right vertical point, the 2XL row may be worth comparing. If you also need a longer body, the chart does not indicate that 2XL provides it.

Take a comfortable cable sweater and measure its finished chest across the body, doubling the flat width. Measure from shoulder to lower edge along the same path you want to compare here. The listing does not say whether its chest numbers are finished garment circumferences or body-size guidance, so ask that question before treating 46 and 52 as directly comparable to your sweater.

Check the banded lower edge

The ribbed hem can determine where a sweater settles, but the source gives no hem circumference or stretch range. Request the relaxed hem width for both XL and 2XL if one size might sit snugly at your preferred waistband. The listed fiber blend is 60% cotton and 40% acrylic; it does not establish a measured amount of stretch. Use the chart to identify the width breakpoint, then confirm chest convention, hem width and length together before selecting a size.
