I would buy a suit or blazer pattern too, but not for baby sizes. I realized oldest son would be making his first communion soon enough and that there simply aren’t any commercial patterns out there for a boys suit. Kwick sew makes a blazer and thats all I could find. I realize boy patterns aren’t typically big sellers and I do understand why, but i think special occasions are exactly when you go looking for boy stuff and are willing to spend money and effort. Boys tend to destroy every day clothes, (and toys, and houses, and their sisters stuff) but costumes and special occasions are good times to gove them your time and attention. At some point, most of us encounter a special occasion. I suppose it would be easier to buy a suit, but often rtw is just plain tacky.
I have been wondering when there will be a four scissors pattern. What a sense of accomplishment that would be!
