Nothing costs more than $200 in the 42-piece collection that features signature "Stella looks" for a fraction of the regular price.
Visiting New York stylist Jesse Garza said the range was as good as, if not better than, McCartney's regular collections.
"She didn't skimp on design or compromise with detail. There is no excuse for every girl not to look good now," Ms Garza said.
The stunning collection featured silk dresses and flowing tops over skinny pants or hugging mini- skirts.
Trench coats, beaded tops and pant suits were in muted colours from black to sage, beige, charcoal and teal blue.
