Hi Colly,
My girlfriend and I had suits made in Bangkok twelve months ago and they are still in perfect condition. We were fitted on day 1, went back to try them on on day 2 and they were waiting for us on our arrival back home (shipping not included). I would highly recommend them:
Chao Phraya Suit
716 Krungkasem Road
Bangkok.
I also found this review:
Chao Prhra ya Suits Exclusive Taylor: Our favorite Taylor by FAR!
Written by Homanded on March 7, 2006.
We had suits and several clothing articles made throughout Asia; including China, Hong Kong, Bangkok, Phuket and Chiang Mai. By far, the best quality was in Bangkok's "Chao phra ya Suit" tailors. Their address is: 712-714-716 Krungkasem Road. Tel: (662) 629-9994, 282-1408. Fax: (662) 282-7355. They had an incredible amount of textiles to choose from, were by far the most proffessional and, even delivered to our hotel for us. We recomend at least 2-3 days, although yes, they CAN have it ready for you in just 24 hours (sometimes, even less). You want to allow one day for a second "fit" and any necessary alterations. Speciafy things such as 1 or 2 pockets, special requests, etc.
Incredible assortment of Cashmere and Cashmere blends. Great silks and textiles. Look through their various magazines, will copy a suit to a tee.
We paid about $140.00USD for Cashmere, Suit, 2 pants, 3 Silk Shirts and a Silk Tie. This was NOT the cheapest we'd been offered elsewhere but trust us, was by far our favorite taylor. .
