The only place I know is on Kapahulu, fairly close to the zoo end of the street, on the Diamond Head side of the street. I checked the yellow pages they don t list anything in Chinatown under vintage clothing. The only place they list is on Kalakaua.
There are great Thrift Stores in Honolulu, I never heard of one in Chinatown and it s not the best part of town. If you want good really good used clothing go to Punahou School Thrift Store. It s on the school campus and they have hours. You d see a lot of good name brand stuff, it s a wealthy Private school with rich parents who donate to that thrift store. Barack Obama went to this prep school and it s one of the elite schools so you will find the thrift store to have some amazing finds.
I have absolutely not idea, but even if there is one, I would highly suggest no limiting your choices to the selection of one local thrift store. Check out Ebay or Etsy.com for individual sellers, and LAVintage.com is my personal favorite for authentic vintage and they ship anywhere for reasonable prices.Good luck!
