hi,
if anyone looking for CS, there's a shop at intl plaza 2nd floor, err think call mama & misse. i think the CS r pretty nice w good workmanship. workmanship prices range from 160 to 260 depending on length. met the tailor b4, she gave me a good feeling that u can really depend on her haha. for material, they can select for u or u buy yrself.
as for material, why not try indian saree? it can be pretty exotic, with a large variety to choose from. price can range from cheaper ones at $53 per 6m cloth which already look quite good, to beaded, embroidered, or silk ones that cost more than 150. for 6m, u prob can make two dresses depending on the length of course, or make a shirt for the groom to make a pair. can try hannifah at little india.
