The standing front shows short low floral shoulder bands and a V-shaped upper centre. Flowers and leaves gather across the bodice and extend into a more pointed waist. A broad mostly quieter gathered skirt begins below. A longer rounded area lies on the floor. Both arms hang down at the sides, with a hand low beside the skirt. Part of the head is missing at the upper border. The darker surroundings establish neither exact shade nor actual occasion.
Compare the pointed transition with a version where individual branches reach farther onto the skirt. Do you want a clear separation or a more gradual distribution? That decision concerns drawing and need not be coupled to a particular outside width. The picture establishes no maker or model name.
Check the upper edge and transition on your own candidate in an ordinary stance. Have real connections explained and add planned shoes. A rounded floor area proves no particular fastening-up system. Assess such an option only if it actually exists and has been demonstrated on the real dress.
