Sample Blouse by Lily White.
A Sew by Sample reflects all of the construction information needed to produce the style.
AKA a Finalized Prototype. I've left it just as I found it w/ pins. Dated 3-23-2018.
No printed care tag...it's a blank. The fabric feels like Rayon. Short sleeves. Elastic at the waist, the front has the twist knot.
Buttons in front are "hidden" as shown. Coral, pink yellow, and white flowers on Black.
