These don't seem to have pattern numbers, or maybe you had to send in to get the catalog to find out what the numbers were. Here are a jacket, morning jacket, and shirtwaist (blouse, often with tailored or menswear-inspired styling, as opposed to something really blousy and frilly) from 1901.
Campus Modes T-8509, March 1937. The peaked sleeves are a very 1930s detail.
Campus Modes T-8510, ad from July but probably released in late March, 1937. I like the depiction of a fun nautical print.
