Margaret Zhang from Shine by Three blog, Lincoln Centre, NYC, September 2012.
The crop top isn't for everyone — particularly if you don't feel overly confident about your tummy — but if you want to give it a whirl without feeling overexposed, style one as Margaret has done with a jacket over the top.
