Probably the most sought-after fabric by visitors from all over the world, Thai silk is celebrated for its outstanding quality, unique designs and affordability. It comes in an array of colours, patterns and plies, and is sold by the yard, or as ready-made clothing and souvenir items such as neckties, scarves, handkerchiefs, shawls, handbags, photo frames, bed covers and the likes. Also look out for the unique 'Mat Mee' Thai silk, a traditional tie-dyed silk from the Northeast of Thailand.
Silk is one of Thailand's great bargains. It can be found all over the city, but care must be taken that you are purchasing real silk and not synthetic fabric. Inexpensive silk items or articles of clothing marked 'Thai silk', like the neckties or scarves for sale at stalls along Sukhumvit and Silom Roads, is not the real thing. Hand-woven silk and cotton from different ethnic and tribal groups in Thailand are more in line with what you're looking for. It comes in a variety of patterns and styles that reflect the cultural and ethnic uniqueness of the people who make it. Although usually cheaper closer to where it was woven, Bangkok has the advantage of having selections available from all over the country.
Prices and quality do vary greatly, but generally good quality silk is easily found at Pahurat Textile Market and at most tailors. Silk gift items and similar products can also be obtained at Chatuchak Weekend Market and many shopping outlets in malls.
