The Belle yellow puff-sleeve dress is described for both on- and off-shoulder wear. Choose the intended neckline position before assessing the fit: changing where the neckline sits is a styling decision, not a substitute for changing the bodice size.

With the neckline on the shoulders

Start by considering where the wide V-neck and short puff sleeves are intended to rest. Ask for a view of that arrangement on the selected size, including the sleeve opening and neckline edge. The listing mentions ruching and floral embroidery on the sleeves, but gives no sleeve-opening measurement or retention details.

A neckline resting where you want it should still be assessed alongside the chest and waist. In the M row, those figures are 34.5 and 26.5 inches, with 14 inches across the shoulders. Confirm the garment-measuring convention before comparing them with body measurements.

With the neckline off the shoulders

This arrangement exposes more of the shoulder line and changes where the puff sleeves sit relative to the upper arms. Ask how the neckline is intended to stay in position and what arm movement is allowed by that construction. Do not infer an elastic adjustment, hidden straps or a specific neckline drop from the styling description.

Use an off-shoulder garment you already own to decide which shoulder position and sleeve opening you prefer. That rehearsal can identify your requirements, but cannot test the fit of this untried dress. If the product’s actual opening and retention details do not answer those requirements, resolve them before selecting a size.

Keep the rest of the dress in the comparison

The documented design includes a satin bodice, tulle skirt, drop waist and concealed back zipper. The satin description does not establish silk fiber, and the material terms do not supply a full composition or lining specification.

S and M both list 45.5 inches in length; L lists 46 inches. The source does not define the starting point or a separate length for each neckline arrangement. Do not invent how far the hem will move when the neckline is repositioned. Request the measuring path for the intended wear position and compare it with a dress you own. The measurement guide helps keep that comparison consistent.
