Paris Fashion Week: Lanvin autumn/winter 2012 During his 10-year span in charge at Lanvin, Alber Elbaz has proven himself one of fashion's finest designers. Last night, he showed he can hold a tune, too. "This is a song for all those I love, and who helped me make my dream come true," said Elbaz as a curtain swept back at the end of the catwalk to reveal the designer on stage with a microphone in front of him, and a velvet-jacketed backing band behind. The show that preceded this singing debut was a tight compilation of his greatest Lanvin hits. The dresses ranged from scuba style to heavily bejewelled, but all showcased that Elbaz knack - through cut, drape and shape - of emphasising everything the women wearing them would want emphasised. His choice of song - Que Sera - as well as the last song during the catwalk show - It Was Just One Of Those Things - immediately prompted some febrile fashionologists to speculate that this show might have marked a goodbye as well as a good excuse to have a party. Most though, simply applauded Elbaz's soulful vocals and twinkle-toed dance moves as he pirouetted down the catwalk working his audience - including Dita Von Teese and Tilda Swinton - like a pro. After Elbaz left the stage, that band kept playing and there was plenty of cake. Read all the latest news from Paris Fashion Week autumn/winter 2012
