I put together a muslin for my pencil skirt the other day. I'm working with my first Burda pattern, 8155. It went together in a snap and just needed a few minor changes.
First, there was too much ease in the hips, so I took it in about 1cm there and down the length of the skirt. Second, I had to admit that I just don't like skirts sitting on my natural waist. I'm too short-waisted and frankly, I find it uncomfortable. I decided to just remove the waistband altogether, and that helped immensely. So, this means that I'll have to draft a facing, but that's no big deal.
I'm definitely getting crinkles at the point where my legs meet my torso, which Fit For Real People says can be fixed by simply removing the front darts. I tried unpinning them, but then the waist is too big. I'm not sure if the answer is just to take in the waist a bit at the side seam? (Or, considering I've already taken the skirt in at the hip, just make the whole thing in a size smaller and omit the front darts?)
I was interested to see that at least one person who's made up this pattern noted that it sits higher in the front than the back. I'm not sure if that's a problem with the pattern, or if that person just has a very similar figure to mine, but I noticed this as well. In these photos, I've removed about 5/8" from the front of the skirt and it's now sitting about level.
So, I guess my next step is just to play around and figure out how exactly to handle those front crinkles, and then draft a facing and be on my merry way. The good news is, once I removed the waistband and wore the skirt lower, it was actually super comfortable. Old habits die hard, I guess!
