i dont think theres any thrift shops in singapore which sells clothes... right? all the thrift shops in singapore sells display ornaments, used cups/plates and items often used in everyday life.. i doubt theres any thrift shop in singapore that sells clothes..
btw faberglass, u can try the Factory Outlet Store (F.O.S.).. im not really sure where the store is located but i rmb seeing an FOS store at town.. the road down frm plaza singapura to Heeren.. i dont know if the store is still there tho.. but FOS sells branded clothes at much lower prices.. cause the goods are rejected by the factory.. like workmanship not so good etc.. but normally u wont see any flaws unless u really go and check carefully
