Why sew other than the fun of doing it if you are into that?? Clothes are so cheap with 3rd world labor I would think it would cost more just to buy the material...
Last month bought some Dockers short sleeve dress shirts (normally priced at $35-40) for $10 each, combination of Sears wanting to get rid of summer clothes, on sale + a coupon.
I wouldn’t dream of making clothes from scratch. I was just trying to do basic repairs on things too good to discard, like the inner lining on a favorite jacket and a 90° snag on a brand new pair of insulated Carhart jeans.
