Before leaving Athens make sure you experience shopping around Syntagma Square and the posh area of Kolonaki, where retail spots are refined, fun and easier to locate. In the realm of luxury, global brands Louis Vuitton, Hermès (open on Sundays), Prada, Dior, Ermenegildo Zegna, Salvatore Ferragamo, Gucci, Cartier, Chopard, Bulgari, Hogan and Balenciaga maintain their own standalone boutiques on prestigious downtown Athenian addresses. The rest of the international high-end brands can more or less be found at local multi-brand stores Luisa World, Linea Piu (exclusive Greek retailer of Chanel and Tom Ford), and Enny di Monaco, as well as the Attica City Link department store.
If you are mostly looking for Greek designers and products that will secure you some admirable souvenirs from this very unique destination, go through the list of the coolest Greek shops that display an amazing range of art, design, fashion, and beauty treasures along with delicacies. Museum shops are a perfect source of sophisticated souvenirs and that also applies to galleries, antique shops, and Greek designer flagship stores. Keep in mind that outside museums and some shops at the historic center (around Acropolis), most stores are closed on Sundays and in the evenings of Mondays and Wednesdays.
