Hi Geesh,
Phuket town is a short shuttle/taxi ride from where you are staying. There are a ton of options for food, shopping, sight seeing. Over the hill towards Karan and Kata Beach there are good beaches and shopping as well as food options. The go carts at the top of the hill are a good time as well if you feel the need for speed without the safety precautions of the western world.
If you can hire a shuttle or driver from the resort you are staying in to get to town or the beach side that will be good. It is expensive to get taxis in Phuket because there is not the same metered system that there is in BKK. The local bus is around ten Bhat but may have gone up a little since I was last there. You can get from Phuket town to the beach on that.
As for the tailor, I had mine made in BKK. I suggest talking with a few of them in Phuket before making any decisions. Remember Phuket is a tourist city, period. They are expecting when people go there from the west that they are ready to spend money. If you have time in BKK I suggest that you get fitted on the first day you are there and then pick up your stuff when you come back from Phuket. Most tailors can bust out a few suits in two days time. Also learn about the fabrics you want before going to Thailand. You can get Cashmere suits or wool or polyester or a combination of all of them. If you don't know what they feel like before hand then you might not get what you think you are buying.
Good luck and safe travels.
