Hi I just returned from Bkk and I saw a shop at MBK with bridal gowns on the upper levels. The gowns are displayed and rotated electronically at the shop's entrance. The gowns are detailed and shimmmered under the light. I must say that the standard was beyond my expectations. Naturally, some of the gowns may have inclinations towards the thai culture but there should be more gowns geared for international purposes.
There is a shop at the Ground level of MBK which makes Men's suits. That shop is directly opposite two shoe shops (u cant miss the 2 shoe shops on the ground level..they are super brightly lit and always crowded with people.)Each suit costs from $150. It's rather cheap, considering the fact that in sg, it costs abt $100 -$200 to rent an OTR suit while for a mere $150, u get to keep the MTM suit for life. The quality of the material used is comparable to that provided by most BS or even better.
I saw this shop at Pratunam (near the 3 hotels Eastin, D'Ma & bangkok palace). If your back is facing eastin hotel, follow the stretch of road along the railway track. Once u reach a junction, there is this shop by the name of Duo Uomo (or something like that). They have this huge sign outside that reads something like 2 suits, 2 silk shirts, 2 pants, 2 casual shirts (and more i cant think of anything) for a total cost of US $300 or $400 which i think is very cheap coz u can't get that in sg! Quality wise, i can't say since I only caught a glimpse of the shop while in the cab.
If you're looking for pants, formal or smart casual, a shop by the name of ALAN has quite good quality stuff. My husband bought some smart casual pants from ALAN for dressing up on weekends & he's quite particular abt quality. He thinks that brands like Giordano and U2 sell overpriced pants which lack quality while Springfield sells reasonable stuff. So i guess if your hubby likes Springfield pants, he may like those at ALAN. There are two ALAN branches in MBK itself - one on the ground level and the other on the 3rd floor (i think!)
Though I didn't purchase any for myself, i hope this info helps any bride/groom looking for gowns or suits or pants in bangkok. Thank goodness I've all BS / Photography stuff settled. Good luck gals!
(in case u're wondering why I can remember everything in detail, that's coz I've been to bangkok 8 times since 2000!) hahaha
