Sevilla

Right on Plaza del Salvador beside the baroque church, Moda re- is a bright secondhand clothing store that looks like any modern vintage boutique – until you read the labels. Why it matters: it is a social-insertion project of Caritas Diocesana de Sevilla (run through its Bioalverde enterprise) that gives collected clothing a second life and creates jobs for people at risk of social exclusion across the province. Prices are low, the stock turns over constantly, and it is one of the easiest ways to shop sustainably in the very center of Seville. Tip: combine a browse with a pre-lunch vermouth on the plaza steps outside, a beloved local ritual.

A five-minute walk from the Museo de Bellas Artes, this small shop on Calle Banos stocks fair-trade coffee, chocolate, textiles and crafts made by producer cooperatives across Latin America, Africa and Asia. Why it matters: it is run by the nonprofit Oxfam Intermon and staffed largely by volunteers, so purchases channel money to small-scale producers paid under fair-trade terms rather than to middlemen. The fair-trade coffee and chocolate make easy, packable gifts, and the handmade jewelry and scarves beat anything in the souvenir shops around the cathedral. Tip: because it is volunteer-run, hours can shift – call 954 227 840 before making a special trip.
