Fabrikated asked, "what won't you sew?"
As I got dressed on this particular morning, I thought that this outfit is fairly representative of my active wardrobe. I made the cardigan, thrifted the turtleneck* and bought the pants RTW.
In 8th grade home ec, I tackled a pair of fly-front trousers in cotton resembling Osnaburg. I learned to make darts and set in a zipper. My skinny teen self needed only minor pattern adjustments, which my teacher helped me with. The color was awful on me and didn't go with any of my other clothes so I didn't wear them much.
Nevertheless, I was pretty fired up and made several more pairs of pants in high school.
In college, I met the son of a tailor. I eventually married him. (The son, not the tailor.)
My FIL expertly took in the back waists of RTW clothing for me. Score! I could buy and wear RTW while spending my sewing time making frosting instead of cake!
My FIL is firmly retired. My middle-aged waist to hip ratio is no longer so atypical. Also, RTW manufacturers have wised up and make several different fits. I can buy perfectly reasonable pants labeled "curvy fit", "contour waist" and "fit 2".
Life got crazy-busy and I squeeze time in to sew for relaxation. Sewing fly fronts is not relaxing for me. YMMV.
T-shirts, on the other hand, are worth my time. My me-made t-shirts provide me with thicker fabric, better fit and softer fabric and seams. I even shave time by remaking thrifted L/XL t-shirts into my size.
I also like to make skirts, dresses and tops. Since I purchased a serger, I sew a lot of knit casual wear. I don't think I have purchased a pair of pajama bottoms in the last 20 years. I did buy a PJ set in my breast-feeding days because I couldn't buy the snap-front PJ top separately. New mother, time-pressed, sleep-deprived = no sewing time.
The top is very ratty now (my baby is 15 yo), but the pants are in good enough shape to stay in rotation.
