Victoria Beckham's Office Secrets

Victoria Beckham´s  team often have the pleasure of seeing her in only her knickers, the charismatic designer revealed at an exclusive personal shopping event at Selfridges last night. "I try everything on - but it's getting less pleasant for them over the years," she smiled.

Speaking to Sarah Harris, Vogue's fashion features director, in front of a group of the label's devotees - most of whom were wearing her designs - Beckham was in town to talk us through an intimate catwalk presentation of her autumn/winter 2013 and pre spring/summer 2014 collections (which prompted spontaneous rounds of applause from the crowd). She was also here to launch her new Quincy bag, which is exclusive to the department store.

Clearly feeling at home when talking about her work, Beckham told us about her favourite parts of each collection, from a midi-length: "It's really sexy"; to "energising colours that make you feel really good"; to her famous pencil-silhouette "Sucky Sucky" dress, which she admitted is "probably not the best technical term for it but that's what I call it because that's what it does!"

She also expressed an interest in designing childrenswear in the not-too-distant future, although it's not on the horizon at the moment. "At some point I would love to do that, but having kids there's so much to do. Working and having four kids is tough, but I will get there. At some point I'd definitely love to - there's a lot of things to do but if you organise yourself in the right way you can get it all done," she said, before attending to shoppers in the changing rooms and giving them styling tips and advice on her designs.

The event comes after Beckham and her husband David released a statement saying that they are donating personal items from their own wardrobes to the British Red Cross Shop Drop for the Philippines to raise funds for the survivors of Typhoon Haiyan. "Everyone has something in their closet they were holding on to, a dress, suit, or pair of shoes they thought they might wear again. Dig them out, bag them up, drop them off and give someone else the chance to buy them, raising much needed funds for the Red Cross aid effort," read a statement.
