The selector for the cropped sweater and wide-leg trouser set pairs two regional labels in each choice: S(US)/M(Japan), M(US)/L(Japan) and L(US)/XL(Japan). Because one choice controls both pieces, compare the top and trousers as separate garments before choosing the shared row.

Build two shortlists from one row

Start with the top. The chart lists bust, top length, shoulder and sleeve length. Then make a separate trousers check using waist, trouser length and hip. A row remains a candidate only if both pieces meet the measurements that matter to you.

Across each adjacent row, the listed top bust, trouser waist and trouser hip each increase by 4 cm. Top length, shoulder and sleeve each increase by 1 cm, while trouser length increases by 1.5 cm. This means moving up for the trousers also changes the top, but by a different amount in every dimension.

Identify the piece that controls the choice

Write down your acceptable row for the top and your acceptable row for the trousers. If both point to the same choice, the paired selector is straightforward. If the top points to one row and the trousers to another, the listing does not say the pieces can be split, so confirm whether mixed sizes are available before ordering. Do not average the two labels or assume the US/Japan notation changes the chart values.

The source calls the type “Loose,” but it does not say whether the numbers are body measurements or finished-garment measurements. It also omits waistband construction, rise, inseam, hem width, knit stretch and measurement tolerance. Those missing details matter when a chart value sits close to your reference garment.

Finish with color and material

Deep Grey, Beige and Camel are the listed color choices. The material is listed as polyester. Choose color only after one paired measurement row works for both pieces; changing color does not change the published chart.

The matching-set size guide provides a reusable measuring sequence. The garment-versus-body guide helps you ask which basis the chart uses before comparing it with clothing you own.
