|I admit myself this is going to be a quick, add on sort of costume. I don't have the money, sew machine or time to make the full blown dress (or the skill probably)|
The dress is dark blue lace from Primark. I have made a saddle like part that attaches with Velcro straps and had the dress/ bustle part attached at the back. From there it has a collar attached to the saddle down the back and held on at the front with a craft foam star broach.
This has been sooo hard without a sewing machine, everything has been hand stitched. I also have very limited resources but I did the best I could, I only hope it looks ok at pony con.
