Vintage Janet Lynn Featherlite Hand Screened Floral Print Robe House Dress

Vintage Janet Lynn Featherlite Hand Screened Floral Print Robe/House Dress - Has a zip front, wide sleeves and an a line cut. Fabric is a satiny textured watercolor floral print. Size tag is not legible. It measures 23" across chest underarm to underarm. 39" in length. Pre-owned and gently worn. There is a spot, up by the neckline, I can't tell if it's a stain or a flaw in the fabric. I'm leaning towards a flaw in the printing of the fabric. I have circled it in the last photo.
