The Daily Mail posted a few candid photos of Kate last week showing the Duchess out and about in London near King's Cross St Pancras Station.
Kate wore a new season Zara checked coat (US$169 / SOLD OUT) - ID by @Giulia_lelepug. The coat is fashioned with lapel collar, long sleeves, front double-piped pockets and vent at the back of them.
She also wore black suede ankle boots we've not seen before. The make is difficult to identify due to the limited photos. One of my readers, Natalya suggests they could be the Russell & Bromley 'Crush Hour' Slouchy Ankle Boot (£185) which appears to be a good match for Kate's booties. However, without hi-res photos we cannot make a confident ID.
