Here is a super cute vintage dress by Helen Whiting. Feels like close to or all polyester. The fabric is a vibrant and fun white and pink floral print, with alternating tiles of black/white check and tan. Zippered back and a bit of a higher waisted cut. This is a head turner, and it's in amazing shape with tons of life left! Here are the exact measurements. (be sure to reference the last photo to see how I measure dresses)

Here are the measurements:

Bust 18"
Waist 14"
Hips 28"
Length 57"
Sleeve 21"

This item is sold from a vintage boutique in Roanoke, VA.
