The MAXCT batwing-sleeve knit dress combines a roomy-looking upper body with a defined high waist in the current Khaki gallery. The selector offers Khaki, Black, Red, Blue and Green, and sizes S through 2XL. The buying question is which size leaves enough space at the fitted waist without making the looser upper section and skirt longer than you want.

Read the waist interval before the size letter

The listing gives waist ranges, rather than one waist figure: S is 64–74 cm, M 68–78 cm, L 72–82 cm, XL 76–86 cm and 2XL 80–90 cm. Adjacent ranges overlap. A measured 77 cm waist, for example, sits inside the listed M, L and XL intervals. That does not mean all three sizes will fit equally well. The source does not say whether the low and high numbers are garment measurements at rest and stretch, recommended body measurements, or another convention. Ask which they represent before treating the upper endpoint as a comfort guarantee.

Use a soft tape at the place where you expect the dress’s high waist seam to sit, rather than assuming it lands at your natural waist. Then compare a fitted dress you already like at the same height. The gallery shows the narrower section below the batwing upper shape, but it cannot tell you how much the fabric gives at that point. If you are near an endpoint, ask for the relaxed waist measurement and the stretched measurement of the intended size.

Use the bust and length to break a tie

Across S to 2XL the listed bust figures are 100, 105, 110, 115 and 120 cm. Length is 98, 99, 100, 101 and 102 cm. Returning to the 77 cm waist example, M and L both include that value, but L adds 5 cm at the bust and 1 cm of length. If you want the upper body to stay close to a reference dress, compare its garment bust to 105 and 110 cm. If you want extra drape, the larger bust figure may be more relevant. Neither number establishes sleeve reach, because the source gives no sleeve or armhole measurements.

Do a quick length check with shoes you would actually wear. Mark 99 cm and 100 cm down from the same starting point on a dress you own; a one-centimetre chart difference may matter less than where the waist seam falls. The source does not define the length start point, so confirm it if knee coverage is important. Its “midi” label is a style description, not a guarantee of where the hem will land on every wearer.

Check the missing lower-body fit

The source calls the dress bodycon and gives no hip circumference, slit or lining measurement. The Khaki lead image shows a skirt that follows the body, so hip room may decide the size even when two waist ranges overlap. Measure your reference dress across the widest hip area and request the same garment measurement for the MAXCT size you are considering. The garment-versus-body measurement guide explains why these two numbers should not be substituted for one another.

Choose the waist position and intended drape first, then compare bust, length and the missing hip measurement. The source calls the piece knitted and mentions polyester/spandex without a precise component breakdown; do not infer opacity, care or stretch percentage from that line alone.
