The pale dress shows a plainer closer long front surface. A shaped upper edge with cup-like curves has no visible shoulder straps at the front. A higher decorated collar area sits above it. Longer fine, translucent-looking outer surfaces descend beside the arms. Warmer-looking, more clearly bounded areas appear at the sides of the waist. Both arms remain down, and handling of the longer areas is not demonstrated.
Compare this plainer front with the more densely floral pale reference. The higher outer frame and the dress visible below it are separate areas to examine. Their position does not establish a detachable connection. The side-waist zones are not secure evidence of completely bare skin either. You cannot determine a particular fibre or appropriate inner support system from this photograph.
Ask for the actual collar, its connection and the areas beneath it to be explained in a similar offer. Then request front and rear views with relaxed arms. Check where the long side areas settle after an ordinary arm movement on the real garment. Record that observation separately from the plainer front surface.
