The pleated and frilled back is very attractive as is the fabric. Afraid I can't read the stamp.
or Jacket of earlier brocaded silk with sprays of flowers in corals, peach, green, ivory silks on a silvery/ivory ground woven with small repeat spot motif, the front with large square neck, front opening, the linen lining with eyelet holes to both sides, the bottom squared and with a pleated frill edged with pale pink silk, three quarter shaped sleeves, the back with wide gussets narrowing to the waist and splaying out to the skirt, edged with horizontally pleated frill, edged with pale pink silk, lined with coarse linen with an oval blue printed stamp, from shoulder to hem 20 in or 50 cm, the back 25 in or 64 cm.
One sleeve is split at the back 3 in or 8 cm and needs conserving. Underarm stains. This bodice was probably a skirt in a former life because the sleeves have old fold marks as if they were the pleats from a skirt. All adds to its fascinating history. The front bodice opening has been pieced so there are horizontal joins, another indication that this piece had a previous history.
