I took a trip down to Barcelona after our family cruise. My bff came to visit and we spent our days sipping drinks on the beach to Unapologetic, coming in at 7am, scarfing down the deliciousness at La Baqueria, and touring the city.
La Humana is a chain of thrift stores I've only found in Southern European countries. For sure if you are in Italy or Spain Google for some locations. They don't close for siesta, which is great from the tourist aspect. Reasonable prices...anywhere between five and fifteen euro for items. 

 Between both days I picked up a vintage pair of 70's checkered overall pants (soon to be shorts), navy blue drop waist dress, colorful cover-up, and sheer graphic tee.
