When Buenos Aires starts to feel like an outdoor sauna, smart porteñas like Gretel Morús manage to stay cool and pretty in pink. Busy lady Gretel, 32, is a freelance fashion designer who is also working on a line of hair accessories. This lady travels—her dress is from Portobello Road in London, her bag was 29 euros from Sara in Cyprus (“My best buy!” she exclaims), her shoes are handmade from Mandarine in Buenos Aires and her sunglasses are Ray-Ban. We also love her pink camo infinity headphones, and (you guessed it!) pink iPod Nano.
