(Note the appearance of toys on my bed in the after shots. It was futile trying to keep them out.) This was technically not a maternity skirt, but when I bought it I needed something quick, it had an elastic waistband, and it was on clearance for about $4 at Target; the perfect storm for buying something I didn't really like and that was really the wrong size. Since the waist fit comfortably, I just decided how far in I wanted the bottom of the skirt taken in, pinned it and made sure that I was taking in the same amount on both sides, and sewed a straight line from the waist to the hem. I also took the opportunity to lengthen the skirt a smidge by letting down the original hem as much as possible--a little over an inch. Serious improvement, right? No more saggy, baggy, shapeless blob skirt here.
This skirt fit fine, but I was just tired of the shape, and felt like it made me look wider (again, one big, bumpy blob). Plus I had seen lots of maternity pencil skirts and was on the verge of coveting one. This skirt is essentially constructed of a series of triangles, so all I had to do was take in each seam to make the bottom narrower, like this:
Now to tackle the rest of my clothes pile!
