The black plaid drawstring shirt dress is described as loose, with a standard collar, long sleeves and cotton fabric. Its chart lists a 150 cm bust at M and 162 cm at 2XL. Those numbers suggest a wide shape, but the listing does not define whether they are finished garment circumferences, flat widths or suggested body measurements. Compare with a shirt dress you already wear before treating the size label as an answer.

Make a two-garment measurement card

Lay your reference dress flat, smooth the fabric without stretching it, and record its width across the chest and its shoulder-to-hem length. Note where its waist sits on you. Ask the store for this plaid dress’s finished underarm width and length measured the same way. The published chart moves from M to L to XL to 2XL in 4 cm bust and 2 cm length steps: 150/104, 154/106, 158/108 and 162/110 cm. Those increments are useful for comparing rows, but do not establish the garment’s fit until the chart basis is confirmed.

Treat the drawstring as a separate question

A drawstring can change the outline of a loose dress, but the source does not say where it is sewn, how far it tightens or whether it alters the hem. Mark the waist position you prefer on your reference dress. Then request a straight-on photo of this dress both untied and drawn in, plus the drawstring height from the shoulder. A broad bust number alone cannot tell you where the gathered fabric will fall.

Choose the row only after those checks

If your reference dress already has the chest room you want, compare its actual width to the verified width of each listed row. Use the listed lengths to judge where the hem may land relative to your own dress. Check the sleeve and shoulder measurements if you intend to wear a layer beneath it. The listed M–2XL sizes, black color and cotton description are starting facts; shrinkage, opacity and on-body fit have not been tested here.
