Hi Marcus, there are lots of bridal studios there offering AD package. Take a walk down the stretch at Tanjong Pagar and you'll probably be spoilt with choices already.
heard from my friend whom also took up bluebay PS @ TW that gowns in Bluebay Studio SG are lesser, more limitations.. she took up an AD package with Di Gio instead.
Marcus, am afraid I can't recommend any. but you can do some research based on the good reviews based in this forum.
beacuse all bridal studios works pretty much the same. plus, different people expectations differ.
more importantly, yourself and your SO mus feel comfortable and like the services and gowns/suits they have.
