Hand made silk dupioni sleeveless dress with sheer bolero approx size 6

Pale sage green silk dupioni dress is fully lined with an embroidered mesh ruffle attached to the lining. Lining is polyester, mesh is embroidered on nylon. Back zip, ribbon belt. Tiny spot on front as shown in photo. I am guessing this is a size 6 but please go by the measurements: pit-to-pit is 17 1/2”, slightly raised waist seam is 15 1/2” measured flat. Length is 50” from back of neck to edge of ruffle. Sheer bolero is poly organza.
