I don't think it's as a result of being a mum that she's dressing as she is, although her priorities have changed I'm sure. We've seen her in slim fit jeans since she's had a baby. The loose fit is on trend, I think it was just the wrong pair of shoes to wear with them on this occasion- they need a heel or pump flat. And with that coat too, it makes it a bit mismatched. But it's so cold in NY and she must be on limited wardrobe as she's only there for the theatre run! I like her basic, comfortable style
