I was re-reading this thread and felt like I should update on the stupidity of the bridesmaid dress that I wore to this wedding this summer. The dress came on time, so that wasn't a problem, but the sizing on the dress was absolutely ridiculous.
I float between a size 14 and a size 16 normally, with a thick waist and narrow hips... I'm also almost 6 ft tall, so I knew I would have to pay extra money to get extra inches at the bottom of the dress. The dresses went up to a size 20... the bridal shop recommended that I order the size 20

AND order an extra yard of the fabric in case more panels needed to be added. I thought this was stupid but, really, I didn't care if the dress was a size 99 as long as it fit me and I could spend as little time as possible thinking about it.
I'm sure you can all guess what happened. The dress came and it wouldn't even stay up on my body, it was so huge! When the dress was being altered, I got entire inches taken off of the sides. The dress had to be completely rebuilt, including the boning in the bodice... thank God for wonderfully talented seamstresses. In the end, the seamstress (who was not employed by the same bridal store who ordered the dress) told me that she had altered the dress down to be an average size 16 dress- so why the HELL did I have to order the wrong size and pay so much damn money for the alteration?
Thank God that wedding is over and done with
