hi sleepysleep
if you intend to get kim to make the 3 gowns, then u must give her ample time k? when's ur AD? actually kim mentioned tt she doesn't really like to make WGs, as if you intend to have a ballgown or puffy A-line, she wld have to make the crinoline (otherwise known as can-can), which she finds very time consuming. If it's a simple WG, she is still quite comfy. In any case, do give her a lot of time...
also bring her designs tt u fancy. she wld only give u opinions to suit u best, but not so much on designs.
my CS material oredi had embroidery on it. there's a similar material tt also had beadings on top of the embroidery.
during wedding preps, u get to learn soso much! enjoy this process!
