Le Boutique Bleue 743-24 Hannam-dong, Yongsan-gu, Seoul (서울시 용산구 한남동 743-24) I loved the building! I love the design! But most of all, I LOVE THE SKT AD WITH EXO!!!! The building's a beauty gallery. It's like a shop for Swiss Perfection products which are displayed as if the building's a museum. There are spas there, I think. See more pictures in this blog ! When you're in Seoul , make sure to visit the place okay? FOLLOW US FOR MORE UPDATES! IMPORTANT NOTE: This post may not be 100% accurate.
