The sash ties in back in a huge bow. You all know how I feel about huge bows :)
My client picked the fabric and I loved the birdie print but I wasn't a huge fan of the stripes at first. I will say they grew on me as the project went on.
I also made a super simple rolled fabric flower headband to match. I used this tutorial and while the instructions aren't great, I just kind of rolled and stitched until it looked the way I liked.
I hope this inspires you to make changes or additions to your basic dress patterns!
