Good luck to you in your quest (I mean Judaism not clothing)!!!
Many places – are you in New York?
Queens, Kew Garden Hills has a large Bukharian community. I’m guessing you’re there. For a yarmuka, tzizis, stuff like that, try Gift World on Main Street. Clothing – not sure in Queens, but if you’re looking for dress shirts or dark pants you can go to department stores like Macys, really anywhere. Hasidic style clothing probably 13th Avenue in Boro Park would be good start.
