Victoria Beckham has saved the dress she wore on her first date with her husband, David Beckham, to one day hand down to their daughter.

The former Spice Girls singer -- who has four children with the retired soccer star -- recently sold many of her previously-worn items in aid of charity Mothers2Mothers. But she admits there were a few items she couldn't bear to part with.

"I kept my wedding dress," she said.

"I couldn't give away the dress I first wore when I went out with David. It was a little high-street suede mini-dress so I've kept that for (Harper)."

The 40-year-old fashion designer recently opened her first stand-alone store in London and though her working life has been hectic recently, she feels "very lucky" to have a good support network.

She told Stylist magazine: "It's pretty full on when I get home, getting the kids' tea, bathing them, doing homework.

"It's a lot to do but I surround myself with the right people and just get on with it. I feel very lucky."

Beckham previously admitted clearing out her wardrobe for the sale -- which saw 600 items auctioned via TheOutnet website -- was "cathartic."

She said: "We went through 20 years of clothes and shoes, hundreds of boxes and rails, and it feels cathartic to have had such a big clear out for such a great cause.

"There was a lot of hilarity, some bad dressing up 'selfies' and a few emotional moments, too."
