She teamed her oversized sweater with chunky leather boots, skinny jeans and draped on her shoulder she looped a large black studded handbag.

Despite her unusual choice of outfits, Emma insists she has her head well and truly screwed on her shoulders.
She told the November issue of Elle: 'Sometimes I feel as though everyone’s waiting with baited breath for the three of us from Harry Potter to do something that will perpetuate the child-star stereotype.
'I don’t know if I’m the least likely person to go off the rails, but I don’t see any need to. It’s not on my agenda.'
She also touched on her interest in alcohol, adding: 'I’m not that much of a lightweight.
'My dad’s great hobby is wine, so it’s always been part of our family life.
'For someone so little, I don’t get drunk very easily. It’s quite a good talent. I’m not challenging anyone to a competition though!'
