For additional recommendations, I can suggest...
IMO wedding gowns are all about the lace. The best lace guy in
Singapore is Kai. Check out Kai Bridal, he's a interesting guy with
alot of great ideals. It is very important to view as many
different types of gowns as possible and discuss it with Kai. What
my wife did was DL myriads of Vera Wang gown designs and then
select a couple of faves and then talk to Kai.
If you have dough to burn, then Vera Wang gowns are simply the
best. Check them out at the Link.
For photographers, Kelvin of Lighted Pixels is among the best I've
seen. I actually changed my wedding date in order to get him to
cover my event. It was totally worth it. I'm heading to Perth with
him for more pictures. PM me for some sample pics of my
wedding.
Make-up, consider TG Goh, considered by some to be 'best' in SG. He
does the make-up for Elle magazine and a couple of other big names.
The most worrisome bit for any bride is that if the makeup would
appear too unnatural and heavy. Kai managed to bring out the
natural beauty of my bride.
