I took sewing classes in November and December 2012 and bought a Bernina sewing machine New Year's weekend. Other than an elephant pillow I stuffed and sewed shut in junior high home ec, I'd never sewed before.
So after a day at work in these, the butt went all baggy. Go figure. In the synthetic fabric, I had to let out the back seam like mad because they're so tight. We'll see what happens after another wash and dry.
