A wedding dress with floral straps offers shoulder decoration without the same long ribbons as the bow reference. Narrow patterned straps lead to a V bodice with pronounced vertical lines and floral forms. Individual motifs extend onto the upper part of the full skirt, whose larger lower area remains quieter. One hand touches near a strap while the other holds a little skirt at the side. That contact does not establish a particular strap adjustment function.
Use this comparison if you want to retain a floral theme while leaving out extra ribbon length. Assess shoulder to waist at a similar scale first. Then choose the V neckline and skirt fullness separately. A smaller shoulder detail does not require a narrower skirt.
Add a relaxed view without a hand at the strap on the actual dress. Try earrings and veil together. You can then choose the visible shoulder outline and its relationship to the face from the worn ensemble rather than treating a posed hand position as a garment feature.
