If you love big brands and you don't want to spend a fortune, you should go to Dress Agency, a store in the roman elegant area of Parioli. The boutique offers great vintage (but not old) dresses, scarves, bags and shoes from Marni, Prada, Valentino, Gattinoni, Gucci and many others. The selection is made by Francesca and her staff. She is very strict and always select the best things in town offered by elegant ladies that drop their wardrobe just to clean up their cupboards and, eventually, makes some money at the end of the season. Dress Agency is located in via Plana 5-A just off Piazza Euclide. Have a look also at sunglasses and bijoux. You will thank me for this wonderful information.
