The Cloud sweater and knit skirt are listed as a two-piece set, but the selector offers one size for both. Read the sweater’s bust chart and the skirt’s waist and hip ranges separately. A size that suits one piece may need checking in the other.

Make a two-column decision

For S, M and L, the top bust is 41, 42.9 and 44.9 in; top length is 16, 16.4 and 16.8 in. The skirt waist ranges are 24.2–28.1, 25.7–29.6 and 27.3–31.2 in, while hip ranges are 33.5–36, 35.1–37 and 36.7–39 in. Write the size that works for your reference top in one column and the size that works for your reference skirt in another. If the columns disagree, ask whether mixed sizes can be ordered; the listing does not offer that choice.

Work through a hypothetical comparison

Suppose your comfortable reference top measures about 43 in at the bust, and a skirt you like measures about 29 in at its worn waistband. The published M top is 42.9 in; the M skirt waist range reaches 29.6 in. That makes M a candidate for further checking, not a guaranteed fit: the listing does not say whether the skirt interval is measured relaxed to stretched or describes body sizes. Confirm the seller’s measurement method and compare hip room before deciding.

Place both hems

Top and skirt lengths each run 16, 16.4 and 16.8 in from S to L. Ask where each tape starts, then mark those lengths on garments you own. Decide whether you expect a gap, overlap or tucked top; waistband height and stretch recovery are missing. The source states 100% acrylic and slight stretch, with Dusty Pink, Misty Blue and Light Gray choices. It gives no lining or opacity detail, so request those if coverage matters.
