The green floral-embroidered mini has adjustable shoulder straps and a concealed back zipper. Its S–L chart gives a bust interval, but only a single hip number and no waist column. Strap length can change where the neckline and hem sit; it does not by itself add room at the zipped waist or hip.

Read the interval as an open question

S lists 27.95–34.25 in bust, M 29.53–35.83 and L 31.1–37.4. These wide overlapping bands are not explained as relaxed-to-stretched dress measurements or body recommendations. Measure a strappy dress you own at the bust with straps set to a wearable length, then ask for the seller’s finished bust width both relaxed and gently extended in two candidate sizes. Ask whether embroidery at the straps or chest changes how the top stretches.

Keep the hip and zip independent

The listed hips are 37.01 in for S, 38.58 for M and 40.16 for L. A hypothetical shopper at 38 in hip might investigate M, but that row is not a fit promise when measurement basis and waist are unknown. Ask for the finished waist, where the back zip starts and ends, and a flat hip measurement at a named distance below the waist. Compare those points with your reference dress before picking a row.

Check the short length after setting straps

Body length rises from 26.77 to 27.56 in across S–L. Mark those endpoints on a mini you already wear after adjusting its straps, and ask whether the seller measures from shoulder, neckline or another point. The source names polyester and spandex but no blend ratio; “satin” in the title should not be read as silk content. A lining and opacity measurement are not provided.
