Hi Hsleed
I think alot will depend on your budget. All 3 designers have very differernt styles
Bridal Veil: Very clean cut. Focus on material and crystals
Tan Yoong: Does dramatic gowns with lots of chiffon and organza
Ted WU: Does great intricate embroidery.
Honestly, you shd go and BS-shop. It's actually fun, and the higher end ones, do not hardsell to you. So you can ask to try on OTR gowns and if you don't sign up on the spot, they ought not to show you black face.
Well, if they do, then i think they do not have gd customer service. So no pt going back to them.
Do check out The Wedding Present. They have great MUA and the designer does wonderful gowns tt have really impressed many brides.
