The black sequin-pocket T-shirt and shorts set has one size selector for both pieces. Each label pairs a US and Japan term, but the useful evidence is in two separate charts: a top row and a shorts row. At the middle selection, both the top bust and shorts hip happen to read 116 cm. Those matching numbers describe different places on different garments. Do not choose the set from one of them alone.

Locate the shine before judging the fit

The front gallery photo shows a bright silver-toned rectangular detail at the shirt’s chest and a strip of shine along the shorts’ side. The side/back view makes the side decoration easier to spot and shows the shirt’s loose outline. The name says “sequin pocket,” but the images do not establish whether the chest detail can hold anything. If a functional pocket matters, ask about its opening and depth. The listing supplies no sequin durability or wash-test data.

Read each part of the paired size row

The selectable labels are S(US)/M(Japan), M(US)/L(Japan), and L(US)/XL(Japan). Treat these as the store’s option names, not a verified conversion between national standards. The top bust values are 112, 116 and 120 cm; its shoulder values are 57, 58 and 59 cm. Top length moves from 74 to 75 to 76 cm. Shorts waist is 70, 76.5 and 82 cm; hip is 112, 116 and 120 cm; shorts length is 54, 55 and 56 cm.

Here is the useful difference: moving from the first to the middle option adds 4 cm to top bust and 4 cm to shorts hip, but 6.5 cm to shorts waist. Moving from the middle to the last adds another 4 cm at bust and hip but 5.5 cm at waist. Each piece gains only 1 cm of listed length per step. If your current T-shirt suggests the middle row while your shorts suggest the last, this page has no independent top-and-bottom size selectors. Ask whether a mixed size is possible before assuming the combined option will work.

Make a two-garment comparison

Lay a T-shirt you already like flat and record its chest width, shoulder width and body length. Do the same for shorts at the waistband, fullest hip point and top-to-hem length. Compare equivalent measurement paths with the source chart, and ask MAXCT whether its bust, waist and hip figures are garment circumferences and exactly where they were taken. A body measurement and a garment measurement are not interchangeable. Leave enough room for the fit you prefer, but do not invent a stretch allowance: the cleaned source says polyester and loose style without a measured stretch range or fiber percentage.

The current product page shows the live Black option and the full paired rows. Check both pieces and the visible decoration before deciding. The shared 116 cm middle-row number is a reminder to read the column heading every time, not evidence that one measurement can stand in for the other.
