You've got the a-line/leather skirt (tick). You've got the right length, this season Celine-esque trousers (tick) and you're reusing your white shirt. But maybe you fancy another top to keep the Celine love in going strong. Oh well then it is a lace top.
For the max effect go grab yourself some Celine in Harvey Nicks, Harrods, Selfridges, Dover Street Market or in the House of Fraser at Westfield. It will set you back some £729 (gulp).
Then in the mid range and very reasonable it is too, this lacey delight from Reiss at £65.
Finally if your budget is stretched then for £39.50 the M&S Limited Collection is giving you this neat number.
Although even though they were using the same model for all their photos it wouldn't have hurt to have put her hair back in a sleek side or back to nape bun...and have lost the pointless necklace for this one shot. Just saying so you know.
