As an experienced seamstress, I can assure you that, sometimes, it is much easier to just make brand new dresses rather than try to alter the ones that were delivered. If the fit was so bad that every single seam needed to be ripped out and every pattern piece re-cut, then why waste your time with the seam ripping and instead get straight to the pattern/fabric cutting? My guess is that Meghan really didn't realize what a complete waste of time and energy it is for the seamstress/tailor to "make alterations" when it's more than just a hem or adjusting the fit by re-doing the zipper. Judging by the photos of the bridesmaids, I'd have sided with Kate too on the matter, but I get that Meghan was the bride and hearing that the bridesmaids dresses were awfully made and fit so poorly was probably the last thing she wanted/needed to hear, especially with all the drama her dad was creating right at the same time.
