If you’re not sure what to wear to the soirees on your social calendar, Fitriani is a safe bet. Inside this Knightsbridge boutique are ruffled, glittering, swirling cocktail dresses that will grab all the attention; the longer dresses, in duchess silk, velvet and chiffon, carry the same Hollywood-style glamour. There is a bespoke service too, if you would rather take home a quirky, one-off piece.
