The red snap-button cardigan lists sizes Small through 3X, but its “bust” row is explicitly labelled “side seam to side seam.” That wording matters: it may describe a flat garment width rather than a body circumference. Treating the S value of 28 inches as a 28-inch body bust could produce the wrong choice.

Compare the same flat measurement

Lay a cardigan that closes comfortably over your usual top on a table. Measure horizontally between the side seams at bust level, without pulling the knit. The listing progresses from S 28 inches to XL 31 and 3X 34 under its side-seam label. Compare like with like, then check whether the snaps close without straining on your reference garment. Ask MAXCT whether these figures were taken flat and whether they are across the front only; the page does not define its exact method.

Shoulder-to-hem length is listed as 28 inches at S, 31 at XL and 34 at 3X. A longer cardigan can change where the bottom snap lands relative to the hips, so compare that point on your reference piece too. The source lists rib detail, long sleeves and a 62% polyester/34% rayon/4% spandex knit, but gives no measured stretch or recovery. “True to size” is a seller phrase, not a substitute for the two garment measurements or a photo of the selected size fully snapped.
