McCartney showed her fall/winter ready-to-wear collection in the ornate ballroom of the Hotel de Ville, Paris' city hall. The collection embodied the British designer's signature sporty yet feminine aesthetic.

"It was very much the country girl discovering the urban edge," McCartney told Reuters TV, adding that she tried to "Mix the two worlds together but in an unexpected way."

Some of the unexpected pairings included girly organza collars with perfectly tailored royal blue blazers and boxy overcoats. In addition, swirly white embroidery provided a feminine touch to sporty bodices of color blocked dresses and tops.

There were no furs or leathers in the designer's Fall/Winter collection, as she is one of the few high-profile designers that refuses to use the materials on moral grounds.

Many celebrities were in attendance, including her ex-Beatle father Paul, who was seen raising his first in triumph at the show's end. Other famous faces in the crowd included Salma Hayek, Carine Roitfeld and Alicia Keys, who is new to Paris Fashion Week. 

"It's so beautiful, the colors are so vibrant but still so sophisticated and chic and strong," Keys told Reuters of the collection.
