From Decades of Style:
This vintage sundress pattern from 1948 can be casual or extremely sophisticated depending on your fabric choice. Either way the dress is beautiful!
The bodice is backless with straps that cross in the back, wrap around the front waist and meet in the back again for a tie. The skirt is quite full but there is no gathering at the waist for a flattering silhouette.
The bodice is lined but the straps are only one layer so the wrong side of the fabric will show. Waistline has inside belt of grosgrain ribbon.
Medium to lightweight woven fabrics recommended. Linen, silk, cotton.
