Now, of course, if you stop the chicest girl in the corridor and inquire as to where she found her perky pleats, her fringed fandangos, she fairly shouts out the 29th-floor windows that she got them in the most plebian shop on the high street, or fished them out of a bottom of a thrift shop bin. Even those among us blessed with a fat purse extol the virtues of mastering the mix, popping a Zara blouse over a Chanel dirndl or marrying a Topshop topper to Céline trousers.
