There are a few recommendation threads scattered in the Girl's Club and Trends+Fashion sections but no specific threads catered to serious discussions on tailoring and alterations.

You can try starting a thread in the Girl's Club (GC) to invoke interests and discussions similar to what we have here.

Although, I advise you against doing the same thing in the Trends+Fashion subforum (which is sort of an abandoned section) since the ladies prefer to talk about beauty and fashion over at the GC instead. Even the female hosiery thread in Trends+Fashion has somehow been taken over by guys who loves to talk about pantyhoses, much to my bemusement.

I think most alteration here is done by our own preferred tailors or if in doubt, Za Altera. Havent seen anyone discussing Sg Wang tailors.
