Gst on tailoring

Dear Sir, I am running tailoring shop with annual turnover of more then 2000000.00. Should I eligible for GST registration. If yes then how much GST rate is for tailoring services. Someone told me that GST on tailoring services is 18% if this is correct then I will loose my half of the business & all my customers are from middle class family & 18% GST nobody can afford. Kindly reply.
