clint >> One stop BS earns the most money from PS, so the moment u tell them u want only gowns, they will change attitude, cuz their main revenue stream is cut off. I was very lucky not to have met service like yours. I only went to one one-stop BS and even though I told them I dun want PS, they were still very nice, let me try on all the gowns etc. Very friendly. You can consider them... Sattine. Look for Francis.
Alternatively, can consider Allure Charix at Amoy Street. They sell their gowns off the rack.
How much did u pay for your Silouette gown??
