The teal Zenana button-down cardigan has a V-neck, dropped shoulders and seven listed sizes, S through 3XL. Its chart gives the garment bust, length, shoulder and sleeve for every size. The useful question is whether it will close over your chosen underlayer without making the hem or sleeves land somewhere you did not intend. A size label alone cannot answer all three.

Begin with the buttoned front

Measure a cardigan you already button comfortably over a similar top. Lay it flat without stretching it, measure across the bust at the same height used in the listing if that measuring point can be confirmed, and double the flat width. The listed bust circumferences are 38, 40, 42 and 44 inches for S through XL, then 46, 48 and 50 inches for 1XL through 3XL. Each adjacent step is two inches. These are garment figures, not recommended body bust ranges. The page does not specify the bust measuring point or the ease allowance, so compare the chart with a garment that fits the way you want and ask for clarification if your result is close to a boundary.

For a worked example, suppose your own cardigan measures 45 inches around the bust when laid flat and fastens comfortably over a tee. The listed XL is 44 inches and 1XL is 46 inches. That makes 1XL the closer bust reference; it does not prove it will button equally well, because knit recovery, underlayer thickness and measuring method are not quantified. If you intend to wear it open, check shoulder, sleeve and length even if front closure is less important to you.

Read the length steps separately

The chart gives 24.5 inches in S and M, 25.5 in L and XL, 26.5 in 1XL and 2XL, and 27.5 in 3XL. Moving up one size does not always lengthen the cardigan. Compare the length of your reference garment from the same starting point, then decide where you want this hem to fall over your trousers or skirt. The listed shoulder width rises from 19 inches in S to 25 inches in 3XL, one inch per step. Because the gallery shows a dropped shoulder, that shoulder number is a placement reference rather than a conventional shoulder-seam fit target.

Check sleeve reach with the shoulder

Listed sleeve length is 19.5 inches in S, 20 in M, 20.5 in L, 21 in XL and 1XL, 21.5 in 2XL and 22 in 3XL. Notice that XL and 1XL share a 21-inch sleeve even though the bust and shoulder increase. Compare the combined placement of shoulder and sleeve to a dropped-shoulder cardigan you own; a sleeve number alone does not establish where the cuff will land on your arm. The listing does not specify sleeve measuring endpoints or cuff fit.

The source lists a 50% viscose, 28% nylon and 22% polyester composition, high stretch, and cold machine wash with low tumble dry. Those details help with laundry planning, but they are not a measured stretch range or a promise about shape after washing. Before ordering, confirm your selected teal size and current price on the product page, and compare the four chart columns with your own cardigan in the order that matters to you: buttoned bust, hem, shoulder placement, then sleeve reach.
