Vintage Wayne kastning for Helga Silk(?) Dress Size 8

Beautiful piece from the 1970s. No materials tag, but it feels like silk to me. Lovely print with great colors for an autumn palette. Measures 18" across the bust and 19" at the hips. Thus, I believe it will fit an 8 or a 6 well. Measures 37" from shoulder to bottom hem. In excellent condition. Fully lined. Has shoulder pads.
