The textured strapless border creates a distinct upper edge above the reflective black body of this dress. Below it, diagonal lines gather towards the hip before the skirt opens around one leg. The trim looks featherlike in the image; its actual composition is not established. The visible contrast between the soft-looking border and the brighter surface is enough to plan two separate fitting questions.
First try the upper section without a necklace. Add your intended earrings, turn your head and see whether their length works alongside the border. Then put on the arrival layer and remove it normally. Watch where its edge meets the upper trim instead of judging the combination only from the front.
Next check the leg opening on a dining-height seat. Its arranged standing position does not establish how the edges will rest while seated. The long lower outline and the neckline trim are independent features: liking one does not require accepting an uncomfortable version of the other. If shortening or changing the opening is necessary, ask for an assessment of the actual dress before choosing it.
