Dots at the neck and sleeves form a dense pale repeat in this close photograph. The ground looks translucent, particularly on the arms and above the chest. Small rounded shapes continue across shoulders and body. The hands rest before the waist, bringing some patterned areas nearer together. The full width of the skirt remains outside the picture.
If you like this density, examine the actual garment from ordinary conversation distance too. Many small shapes may look more like a connected surface there. Decide whether that is your preferred effect or whether you want each dot to remain more separate. A comparison with wider spacing is useful for the second possibility. Do not treat the close detail as a substitute for the full view.
The high neck already carries substantial drawing. A necklace adds another clear shape, so begin with a restrained jewellery trial before adding more. For the sleeves, bend an arm and hold a bouquet rather than inspecting only extended fabric. The dot appearance alone cannot establish the material or how each pale element has been attached to the garment.
