Some want to practice their English by talking to you. Over the years we have become friends with many of the vendors that we've dealt with. You can bargain the price. It is best to shop around if you have time and obtain at least three comparisons on the item that you are interested in. Items such as bags, souvenirs, silk, clothing are plentiful.
Tailors are everywhere and usually in close proximity to each other.
If you are purchasing any tailor made item give yourself enough time to have the clothing made properly without haste. We suggest a week. Give yourself time for the first fitting, tailoring alterations and the final fitting. If you have something you must alter in your home country because you didn't have time to have the tailoring done properly in Thailand, you will lose much of the savings benefit as you would by having it done by the Thai tailor. To avoid having to carry a tremendous amount of luggage home tailors can ship the clothing to you.
