Vintage 1970s/80s Nani Honolulu Floral Maxi Dress

Vintage red floral caftan dress by Nani Honolulu. Best guess late 1970s to early 1980s based on the style of the button. Unlined, has one side pocket on the right. 100% cotton, USA made. Good vintage, preowned condition with minor signs of gentle wear. No size given, estimated modern size S, maybe up to smaller medium.
