70s Patchwork Full Skirt & Blouse 80s Vintage Seminole Style S/M Origins

This is such a striking set, wearable as separates or together for maximum impact. I see Native American influence in the design, possibly Navajo, or perhaps Seminole. I am also reminded of the "Patio Dresses" that were very popular in the 1950s and 1960s, particularly in the American southwest. The top is sleeveless, with a wide neckline ruffle that adds a small "cap" at the shoulders. The skirt has an inset waistband and three gathered tiers. There is extensive piecing of colorful fabric, along with rickrack trim in the same colors. SIZE: The blouse is labeled M, and the skirt S Measurements Inches Cm Blouse: Bust 38" 96.5 Blouse: Bottom hem circumference 40" 102 Blouse: Length 20" 51 Skirt: Waist 28.5" 72.5 Skirt: Hips Free Free Skirt: Sweep 116" 296 Skirt: Length 30.5" 71.5 FABRIC/COLORS: Primary color is light gray - fabric is lightweight. The gray of the blouse is slightly darker than the gray of the skirt - see closeup with my thumb on the right and finger on the left with blouse fabric on the upper right and skirt fabric lower left. The colorful piecing is done in strong shades of red, purple and dark green. Labeled 100% cotton, and dry clean only. TAGS: Origins, Santa Fe, made in India CLOSURES: The skirt closes with a pair of small red buttons and a short nylon zipper. The blouse slips on over the head. CONDITION: A few minor issues. I found a couple of small yellowish spots in the tiers of the voluminous skirt - see closeup with pens pointing. There is a small hole from frayed seam at top of bottom tier, an easy repair - see closeup. Sometimes I think I see subtle color bleed of the red onto the gray fabric - see last closeup for my best effort at showing it.
