Hi
I will be travelling to Hong kong for a week in January and I'm thinking of going to mainland china for a day trip to have shirts/suits tailored. I've done that in guanzhou before and was hoping i could switch this time for a closer place. hence I was wondering if:
1. are there similar markets options to buy textiles and tailors as well as other bags replicas in Shenzhen as in Guanzhou?
2. is it worth it (cost wise) to do bespoke shirts/tailored suits there compared to Hong Kong? or Guanzhou?

thanks in advance
