A purple full skirt occupies considerable length and width here. The upper section has a clear V direction between broader shoulder areas. Larger folds descend from the waist, and a front opening reveals leg and part of a shoe. The hands sit beside the upper skirt. The picture therefore connects a distinctly drawn upper point to a broad lower surface, offering a different comparison from the closer options.
When choosing narrow or full, compare this relationship with a closer candidate that has a similar neckline. Keep strap width as comparable as possible. You then assess the amount of skirt rather than also selecting an entirely different shoulder frame. Decide which outline you enjoy from front and side and how much movement you want below.
Let your hands fall freely at the fitting and walk several steps. Check the real opening and shoe without pulling fabric outwards. A full skirt may create another area while seated, so include that view and ask about actual hem length. The purple impression provides a search direction rather than a binding shade for other offers or evidence of a particular fabric type.
