The Sweet Love Peter Pan knit dress has a pearl-button front, but the listing calls those buttons non-functional. Its concealed side zipper is the stated way in. Before ordering, separate the dress’s decorative center line from the opening you must use and the stretch ranges you must fit.

Trace the dressing path

Ask for a side photo with the zipper fully open and closed. Confirm which side it is on, its opening length and whether it crosses the waist. A zip that stops above the hip may affect how easily the dress goes on even if its listed chest range looks suitable. The listing does not give those zipper dimensions, so do not assume the front unbuttons.

Compare both ranges, not one label

S lists 14 in shoulder, 32–36 in chest and 24–28 in waist; M lists 14.5, 33.5–37.5 and 25.5–29.5; L lists 15, 35–39 and 27–31. Chest and waist intervals overlap between adjacent sizes. Measure a knit dress you already wear at the shoulder, chest and waist in its relaxed state. Ask whether the published intervals describe garment stretch or recommended body measurements before matching your numbers to them. A shopper with a 35 in chest and 29 in waist, for example, cannot decide from chest alone: the S waist interval ends at 28.

Keep the silhouette details in view

Every listed size is 31 in long. Mark that length on your reference dress from the same starting point after confirming how the seller measures it. The Peter Pan collar and lace-trim cuffs are visible design choices; request cuff opening and fiber composition if either affects wear. The source says the knit stretches but gives no measured recovery or percentage.
