The gingham picnic cami dress has two decisions on the product page: S–XL size and a separate Dress Length choice of approximately 32 or 37 inches. Its chart mirrors those two lengths in every size row. That five-inch choice will change the intended hem more than moving between adjacent letter sizes, so select length deliberately instead of hoping a larger size will make the shorter version long.

Choose the hem with a dress you already own

Find a dress whose coverage you like and measure from the shoulder or strap point to the hem, noting the exact starting point. S and M list 32/37 inches; L and XL list 32.5/37.5 inches. The gap remains five inches. For example, if your reference dress is about 36 inches long from a matching point, the ~37-inch option is the closer published length. The ~32-inch option is roughly four inches shorter than that reference. This is a comparison, not a prediction of where either hem will fall on a particular body: MAXCT does not specify the chart’s measurement points.

The dress is described as unlined, with a swishy skirt. If opacity is important for the color you choose, ask about the actual fabric and consider the underlayer you would wear. The listing does not provide a skirt circumference or fabric-opacity test, so the length selector alone cannot answer either question.

Then fit the upper section

The S row gives 30 inches at the chest and 26 at the waist. M is 31.5/27.5, L is 33/29 and XL is 34.5/30.5 inches. Compare those figures with a similarly shaped dress at matching points after confirming whether the published figures are finished-garment or body measurements. The square neck, thick straps and concealed back zip define the structure; the waist sash may change the look but has no published adjustment range.

Before checkout, verify that the cart shows both the intended size and the ~32- or ~37-inch length, and that the combination is available. This is especially useful here because the chart prints both lengths in one row while the product has a separate length selector.
