I tried various combinations of seams before sewing this fabric. My Singer Stylist has a stretch stitch that looks like this: lll. It works exceptionally well for this 4 way stretch fabric. At first my thread kept breaking but after changing the top and bobbin thread to Metrosene Plus, it worked like a dream. All seams were sewn with this stitch including the hems and waist area. I used 1/4" elastic for the waist which was also copied from the RTW pair. Just as a reminder, you have to make thin elastic about 1/3 smaller than the usual 1" waistband elastic.
When copying the pajama bottoms I was lucky that the fabric had a stripe running lengthwise. It made it easy when marking the straight of grain. I still had to true up the pattern but it was fairly easy after sewing the initial pair.

|Evidently when I traced the back waist area, I over stretched it.|
