1960's EMBROIDERED SHEATH DRESS vintage 60's M

Looks like the texture and color of linen, but I believe this is a synthetic or a blend. Beige background with sage/olive green/ivory floral embroidery all over. Fully lined. I think this is handmade. It's done very nicely! Back metal zip closure. Matching belt included. Overall excellent condition, although I see some wear to the belt, particularly the buckle. The dress itself is fabulous! Fits like a M, please compare the measurements below with a dress you have at home that fits well. ACTUAL GARMENT MEASUREMENTS (no stretch) Bust: 37.5" Waist: 30" Hip: 39" Length: 42" (K4)
