A party to celebrate the opening of PPQ's pop-up Jackdaw store at London's Burlington Arcade. The two Geldof girls sipping Red Bull and rifling through the rails of clothes on display. So far, no surprises. But things got a little heated last night when both Peaches and Pixie fell in love with the same dress – a patchwork number from the A/W '09 collection. We saw the youngest Geldof run across the shop floor, grab it off the shelf and pull it over her jeans in the middle of the room. Her sister Peaches wasn't being left out of the action and crowded in to claim it for herself. The two were seen having a heated, if tongue-in-cheek (we think) fight with PPQ designer Amy Molyneaux over who would get to keep the dress. PPQ model Pixie clearly has the strongest voice (or perhaps Amy thought since Peaches already has a collaboration with PPQ, she'd take pity on the other sister?), because she won the fight and emerged from the store opening clutching her prize. She's apparently already decided it's her outfit for an upcoming event she's got to attend next week, so it stayed in a shopping bag this time. But that didn't stop Pixie grabbing another A/W '09 dress – the striped black and orange number – to change into that night. If only our shopping sprees were so easy!
