Bought the Côte&Ciel Spree Messenger Bag (Grey Melange) from city’super at Harbour City in Hong Kong for HK$1,250 (S$200). The size I bought is medium and it will fit up to 13″ laptops.
I think I just become a fan of Côte&Ciel bags, their bag design is unique and nice. If you want to get their bags in Singapore, you can check out Cumulus at Wheelock Place or their online store cumulus.sg.
