Project of clothing business in Thailand

My name is ishvari, from France. I have been traveling a lot to Thailand and spending a lot of time here as tourist,  but now I'm starting a clothing business (production made in India),  and I would like to know what kind of formalities and papers would I need in order to be able to sell my clothes legaly in Thailand,  in market for example...or Have my own clothing company base in Thailand.
And the 3rd option would be even opening a shop in Thailand...
But most probably I will stay with the market  in Thailand and having a legal business base in Thailand for now...
Thanks for your advice
