The strap dress with wide skirt layers has a floral bodice and broad patterned straps beside a V neckline. A hand holds the large fine outer fabric out at the side. A more fitted lower line remains visible beneath it, while some fabric gathers at floor level. The pose emphasises external width rather than demonstrating a particular step sequence.
Take a question about the complete construction to your appointment first. Have all supplied layers shown together on the actual candidate and let the skirt fall without hand support. Check where the lower pieces sit beside your shoes. Only then compare an ordinary step and a careful small turn. The held-out surface does not answer those questions independently.
If you enjoy the spread shape, also decide whether and when you want to gather fabric yourself. Try the hand position with your intended shoes and any other task you expect to perform. For a dance without constantly holding the hem, release it during the trial accordingly. The attractive outer fullness and the handling you want remain separate choices.
