1940s Siren Sundress

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.

    This dress was on my list from the moment I saw it, despite some difficulties I had read people had with it the model is stunning. Eventually I made it by hand while on vacation and did the same adjustments as most, like taking off some length of the fronts, and I lined the straps as to have more body on and a nice ‘wrong side’.

    I think the model is very elegant and sophisticated, which makes up for the fiddly-ness it has while wearing it (redoing straps and keeping the back skirt closed decently 🙂
