The MAXCT cable-knit V-neck sweater is listed in Light Gray and Cream, with S, M and L choices. Its product measurements give more than a letter size: bust, shoulder, sleeve and length all change, but at different rates. If you are choosing between two sizes, the useful question is whether you need more room around the body, more reach through the arm, or both.

Start with the garment bust, not the letter

The listing gives bust measurements of 41.3 inches for S, 42.5 for M and 43.7 for L. That is a 1.2-inch step between adjacent sizes and a 2.4-inch difference from S to L. Measure across the chest of a sweater you already like when it lies flat, then double that number to compare like with like. A sweater measuring 21 inches flat across the chest has about a 42-inch circumference by this method; it sits between the listed S and M figures. That example is a comparison method, not a prediction of how either size will feel on your body.

The source calls the knit moderately stretchy, but does not quantify its stretch or give a recommended amount of ease. If your reference sweater is much thicker or more fitted, its chest measurement alone will not settle the choice. Check the hem and upper arm of your reference garment too; this listing does not supply corresponding widths for the MAXCT sweater.

Check where the sleeve measurement begins

The chart lists shoulder measurements of 22.2, 22.6 and 23 inches from S through L, while the listed sleeve lengths are 16.8, 17.2 and 17.6 inches. Both figures rise by 0.4 inch per size. A shorter sleeve number beside a broad shoulder number can occur when the sleeve is measured from a shoulder seam rather than from the neck, but the source does not specify its measurement points. Do not add the two figures and treat the sum as a guaranteed neck-to-cuff reach.

Instead, lay your best-fitting sweater flat and measure from the center back neck, across the shoulder and down to the cuff. Ask MAXCT for the same path on the intended size if sleeve coverage matters. This is especially useful when a coat sleeve needs to sit over the knit without a long cuff bunching inside it. The V-neck shirt-layer guide offers a separate way to plan the neckline with an existing shirt.

Place the hem and neckline in your outfit

The listed sweater length progresses from 22.2 inches in S to 22.6 in M and 23 in L. Compare that with a top you wear over the same trousers or skirt. If the hem falls where you want it in S but you need M’s chest room, the half-inch-scale length change is part of the trade-off; do not assume changing size will fix the neckline position. The V-neck depth and opening width are not measured, so use the gallery to judge the visible styling and ask for a neckline measurement if a collar, camisole or workwear coverage depends on it.

The listing identifies a 100% acrylic cable-knit with cold machine washing and low tumble drying in its care text. Check the label on the delivered item before washing. Choose the size after comparing a reference garment on the dimensions that matter to you, then confirm the missing shoulder and neckline measurement points rather than relying on the size letter alone.
