Nicholas Kirkwood - These black leather Delfi ballet flats epitomise Nicholas Kirkwood's penchant for classic feminine nuances mixed with modern innovation. They're crafted in Italy with deep-cut vamp to flattering the squared toe – note how it elongates the leg – then set with a drawstring fastening across the back, set with the label's signature faux pearl, reworked as a toggle. Pair them with tailored trousers and a blazer for a smart daytime look.
