Hmm..maybe..but it's a bit late to ask them to have it done before your big day.
My wedding is in July. How long does it take?
My dress took roughly 4-5 months, but for some women it took much longer (keep in mind they close the factory in February for Chinese New Year).
But be warned - just because they can say they'll get it to you in time and that they can do it doesn't mean they actually can. There are lots of women in this group that had awful experiences with them (myself included).
What was wrong with your dress. I saw your oics and it looked lovely.
All info regarding problems with my dress can be found here (along with all the other negative experiences that other brides experienced):
