The skirt is just a tiered skirt which is easy and those are lace parts. The bodice looks a bit more complex but if I think hard enough, I could probably piece bits together and make it up. Maybe i’ll order some cheap fabric to make a toile.
I’m wondering if she is using clips on her headband? You can buy them now that are hard headbands covered in fabric to look like that but I like the look of it going round the back!
