Hey, I found this really awesome Etsy listing at http://www.etsy.com/listing/159265909/vintage-1960s-sewing-pattern-simplicity
Decades of Style sundress #4003 1948 Siren Sundress Size B (38" Bust) needs 4.33 yards of 45" wide fabric, or 3.0 yards of 60" wide fabric
McCall's 4318 Misses' Vintage 1950s Lounging or Patio Culottes, Bolero and Belt Sewing Pattern by DRCRosePatterns on Etsy
Would probably do better with vertical plus bust darts instead of angled ones, but not too hard to modify. Love the bow detail.
