After much consultation with Jono and Mama Gypsy, I chose Butterick 6855, and Mama G helped me grade it up to my size. And then sew it, all in the space of a day. Seriously, that is how easy this dress is, and it was fun too!
My first version, made for the meet, was aqua and the most 60's pattern I could find in my local store. I couldn't even find some paisley! My lunch hour was frittering away, so I grabbed the roll and bought the lot - I seem to always find fabric when it is at the end of the roll. I have no idea if this is luck, or I am just several steps behind the other sewists and quilters of Palmerston North!
The 60's. Modest. Who would have thought?
