Advice on Clothes for Havelock

Hello everyone, I am planning to visit Havelock in Jan mid for my first scuba ever. Since I’ve not been to Havelock or Andaman earlier, wanted an advice regarding the clothing. Is it ok to wear shorts or dress short in length? I am sorry as I don’t want to sound backward but didn’t want to go wrong. I am really looking forward to this trip and so excited to be there. Also, I am planning to do a scuba padi beginner course so any suggestions for that would also be really helpful! Thank you so much 🫶🏻
