The Garden Gingham Midi Dress has a sweetheart neckline, ribbon ties, tiered half-length puff sleeves and a concealed side zipper in its product description. The useful sizing question is at the bodice: the listing gives a chest and waist number for each of S, M, L and XL, but it does not say whether those are finished-garment measurements or recommended body measurements. Confirm that point before treating a chart number as the amount of room you will have.

Read chest and waist as a pair

The listed pairs, in inches, are S 32.5 chest / 24.5 waist; M 35 / 26; L 36.5 / 27.5; and XL 38 / 29. Moving from S to M adds 2.5 inches at the chest and 1.5 at the waist. Each next step from M to L and L to XL adds 1.5 inches to both. That matters if your reference dress is close at one point but generous at the other. Choosing from a single number hides the second constraint.

For example, suppose a dress you already own measures 35 inches at the chest and 27 inches at the waist, measured flat and doubled. The listed M matches its chest number but is one inch smaller at the waist; L is 1.5 inches larger at the chest and 0.5 inch larger at the waist. Those comparisons identify what to ask about, not which size will fit: first establish that the seller’s chart uses the same finished-garment method as your reference. If the chart instead describes body measurements, use the seller’s intended fit guidance rather than this direct garment comparison.

Keep the neckline and zipper questions separate

The description names ribbon ties and a concealed side zipper. It gives no measurement for how much, if at all, the ties change the neckline opening, and it gives no stretch figure for the bodice. Ask for a photo of the neckline tied as shown and for the finished chest and waist measurements of your preferred size. The zipper tells you where the closure is; it is not evidence that a snug waist will relax.

What the repeated length can tell you

Each size row says 44 inches long. The source does not specify the measurement start point, so this is a listed length to compare, not a guaranteed hem position on a particular body. Measure a dress whose hem you like from its stated or photographed start point, then ask MAXCT to confirm the corresponding point on this dress. Sleeve and hip measurements are absent too. If those determine your comfort, request them before ordering. The product page is the place to check the current size options; this guide helps turn its four chest/waist pairs into precise fit questions.
