On saturday I went to de Dos De Market, at Plaza Dos de Mayo. You have like 2 "sections", one with second-hand things and another with design things. It's every saturday this month and in June. From 12:30 to 21:00 (First it was said that only to 17:00). In the design sections you can find really nice things, I really liked a t-shirt stand, the brand was Hi-Hirvi, really good!! Other brand where Julieta Aytas, she has some nice paintings, you could find a lot of jewelery like Isana, Mumu.Joyas and Mora Efron, Another t-shirt brand, really nice was Pandarman which have also a lot of cool pins. Clothes, Puracostura Vintage and clothes and accessories for children, Ponytail. There where other brands too and all of them very nice and with beautiful/cool stuff.
