Hi Sok Fung,
Yup, I heard Margaret Brides specialises on lace as well.
I didn't go to the tanjong pagar stretch at all after hearing a few horror stories. Sometimes, when I'm just walking down the road to get to a restaurant, they will try to pull me in as well!
I'm with Divine couture, and really like their gowns and A* for service in my experience. They are tasteful designers and will advise such that your gown makes you look nice (e.g. what enhances height etc), whilst taking into consideration what you like (e.g. I have this thing for off-shoulder gowns, and they suggested these detachable shoulder attachments).
Price wise, my MTM package was slightly cheaper than Wedding Present, Bridalveil etc, but think their prices now will prob be the same (around 3988).
Hope this helps. Just my opinion (and from some friends' feedback), but some one-stop bridal shops quote you cheaply for the basic package, but most of their profit margins lie in the photographs so don't be surprised if they really hardsell you when your PS is over. The total cost can be the same / more, compared to when you use a wedding boutique that is tied to a separate photographer. For me I don't intend to get a whole lot of photos, so really didn't want to undergo the hardsell.
Happy searching - it's quite fun!
