I knew starting out that the skirt would probably be the most time consuming part of the Princess Celestia dress. Considering that I broke it into two parts in my build list, it was a fair bet. Also, considering that I was making a bum roll for the first time in my life, I assumed that I needed some extra time. I allotted 3 hours for the underskirt, and finished it in about 4. I’ve discovered that the pattern making is an extra hour than I thought, so I’ll have to accommodate that for the Vanellope dress. Luckily, there isn’t a whole lot of patterning in Vanellope’s dress. It’s 90% pleating.
☒ Trace & size pattern (bum roll)
The original link I had for “how to make a bum roll” ended up confusing me, so I looked around until I found this site, which I had used before for their corset generator. Anyway, their version was much easier and able to be altered to a child’s size than the first one I had seen.
☒ Make bum roll
☒ Trace & size pattern (skirt)
I decided my best bet for the skirt was to make a classic gored skirt. For those that don’t know, a gore is a triangular shaped piece of fabric used to make a skirt wider at the base than it is at the top. For this, I measured the bum roll, which was 28″, divided that in half and added 2 inches to each piece, so that I was left with 16″ a piece. Then, the hoop skirt measured at 30″, so I added 3″ to the length. I measured out four rectangles that were 16″ by 30″ and cut those out. One piece was left whole for the center front. One piece was cut in half lengthwise for the center back. The last two pieces were cut into right triangles by drawing a line between opposite corners. Important part: The angles must be opposite to make the gores work properly.
☒ Cut out fabric
I cut out each piece and serged it to prevent raveling.
☒ Assemble skirt
Here’s where the part about the opposite angles comes in. Take your two right triangles and lay them, right sides together, with their vertical edges together then sew them together. This will leave you with an almost equilateral triangle.
I then sewed the rectangular pieces to the angled sides of the triangle to make the complete skirt
I now wish I had sewn the long sides together in hopes that the sides would be longer than they are, but I pinned up the ruffle on the hoop skirt. It looks really cute with the ruffles either way.
☒ Attach to bodice
As the skirt was slightly larger than the bodice, I gathered it on and let it hang.
As it was already a little short, I decided to leave the hem serged instead of doing a true hem. I don’t think anyone will see the difference.
