Sheer navy blue blouse with lace and ruffles detail

Sheer navy blue blouse with beautiful lace detail, and ruffled neckline. Cuffs are finished with covered buttons. Very lightweight material allows it to drape beautifully. No tags no this item, believe it is polyester. Pit to pit 21" Shoulder to hem 24" Based on measurements, I am calling it a medium because I believe it is meant to be worn loose fitting.
