The sleeveless open-front cardigan has a shawl collar, pockets and a listed S–3XL chest-and-length chart. Because your own sleeves pass through its armholes, the missing armhole measurement may matter more than the letter size when you layer it over a shirt or sweater.

Start with your under-layer

Put on the blouse or knit you intend to wear beneath it. Measure the shoulder and upper-arm area of that layer, or compare it with a sleeveless vest that already clears the sleeve without bunching. Ask MAXCT for the flat armhole opening and shoulder width of the chosen size. An open front may let the body drape, but it cannot create clearance at an armhole that is too narrow for the under-layer.

Use the chart for proportion

The published chest increases from 44 in in S to 54 in in 3XL, while length rises from 31 to 34 in. For a longer line over trousers, compare the shoulder-to-hem length against a cardigan you own. The text does not say whether the chest value is measured with the open fronts touching or lying naturally, so ask for that method before inferring how much body ease you will have. The listing names a lightweight sweater knit of 95% polyester and 5% spandex, but gives no weight or warmth test.

Finally, the pockets are described without opening, depth or closure measurements. Ask for those if you expect to carry anything heavier than a small personal item. Check the selected size in the cart after resolving armhole and length fit.
