Emily Zak, Acting Executive Fashion Editor, British Vogue.
What I love about Emily's outfit (apart from that scrumptious Chanel bag looped over her arm!) is the leather top/corset/bra top? she has layered over her shirt. Okay, so the lingerie (and leather) trend is big this season but not all of us can (or want to) put our fleshy bits on display to the world, even if it is under a jacket or cardi. So how Emily is wearing hers is perfect: it is up-to-date but in a subtle way. AND, crucially, no stomach crunches are required :)
I really like the leather bra tops, particularly the buttery caramel biker one, by Blouson Noir (stylist Melanie Ward's line of clothing), and I think Alexander McQueen did some for SS 2010. No doubt there are lots of high street versions available as well that won't break the budget.
And note Emily's cowboy ankle boots? Saw a couple of the Vogue girls wearing these during LFW... Time to dust them off again, perhaps?
