Light lines spread across the dark blue skirt and stand out against its base colour. A shorter front reveals the legs while the back falls further. The more angular-looking upper edge differs from a softly curved heart neckline. A small pale bag appears beside the dress. For comparison, consider pattern scale, hem transition and neckline together, rather than assigning a fibre or material from the surface.
Check the actual fit
Look at a similar pattern from normal conversational distance and close up. Check how the front joins the sides while walking. Compare your shoes with the shorter hem, and ask whether an alteration would change the visible pattern or edge shape before agreeing to it.
Use the image to compare visible shapes, then check comfort, alterations and product information on the real garment. A photograph does not replace a fitting.
