Brussels is a paradise for lovers of vintage and second hand shops. Buy cheap and sustainable clothing and accessories for a fraction of the price in these boutiques.
You can also buy curious objects at one of the largest flea markets in Europe, located on Place du Jeu de Balle. If you don't find what you're looking for, you might find it at one of the many flea markets in town.
Good to know, there are two months that you should focus on if you plan to take advantage of your stay in Brussels to make some good deals. The months of July and January are the preferred time for regular shoppers as this is when the sales are on.
