This dark blue and violet-looking reference offers a colour idea for a colour-gradient wedding dress. The long garment has thin straps and smaller tied upper-arm sides. A shaped front edge sits above a widening skirt with small star- or point-like details. Several fine-looking areas overlap, showing blue and violet sections in different brightness. Both hands hold the skirt apart at the sides. Head and shoes are not completely visible. The image establishes neither a particular dyeing process nor a wedding occasion or the exact inner layer of an available garment.
Mark the colour you want to find and its position first. Have the actual candidate shown with relaxed hands next, so distribution is visible without spreading. Ask about included layers and the offered colour version. Try your underwear and shoes with it. A cloth sample can add colour information without replacing placement on the whole garment. Choose bag and jewellery afterwards. Another skirt width needs a genuinely offered model and its own complete view rather than a presumed modification to this photographed shape.
