If you are looking for some funky clothes from local designers, head to Palermo Viejo. You won’t necessarily find bargains, but you will be able to buy one-off creations that no one else in your hometown will be wearing.
In Microcentro, Florida Street is the main shopping area for all the big brands. San Telmo’s main street Calle Defensa is where you can pick up some amazing antique pieces. For authentic souvenirs, why not try the Feria de Mataderos? The market-like atmosphere here is so much fun you may end up staying for hours. Whatever you do, make sure you take home some leather goods from your time in Buenos Aires. With all that beef-eating going on, it’s not difficult to find stylish, well-crafted leather goods for much less than what you’d pay anywhere else.
