I love the navy seersucker in this, and it is a gorgeous match for the delicate blue floral broderie skirt, finished with navy spot lace.
This one sits short at vintage length so bloomers for modesty are recommended!
But it is lots of fun, with a full skirt and tie through straps into the back elastic panel.
All of these fabrics are vintage, and I did to a test prewash of the navy and it was fine, however while I was sewing it did leave a slight blue tinge on my fingertips (came out with water). So I can't guarantee that the colour won't run, however hopefully with a handwash in cold water it should be fine! But I have discounted it just in case...
