The huge Trey Seegle painting spelling out the word 'YES' at the back of the runway, truly set the tone of the Stella McCartney Spring/Summer collection.  Gone was the pessimistic and over-intellectualised response to the current economic climate that we saw from New York to Milan last season. Instead, McCartney opted for feminine, fun pieces that oozed optimism.

"I want women to feel happy," she told Style.com backstage. "There's been a lot of sternness on the runway and I just kind of wanted to disperse all of that and just bring a summer energy."

This translated into huge ruffle detail on asymmetric mini and maxi dresses in bright colours like oranges, pinks, reds and yellows. The soft silhouette marked a change for Stella, who is usually about about the structured tailoring."I'm a lot less over the top than a lot of designers so for me, that was a big deal".

Although her classic blazer did appear, the tailoring was a lot more subdued and relaxed that we've ever seen from her. Natalia Vodianova opened the show in an ivory ruffle neck jacket that was a far cry from the boxy boyfriend styles that the designer showcased last season.

It wasn't all about bright colours though. Stella also showed a lot pieces in browns and creams too.
