http://netbride.com/exclude/sizecharts/levkoff.htmDress: Bill Levkoff 929 That is the chart from netbride regarding sizing.Do you follow it exactly?My girls are the following sizes:Girl One is normally a 16/18 dress size and her measurements are 43/39/44.5 (b/w/h)Girl Two is 18/20 and her measurements are 47.5/44/47.5Do we order based on the biggest measurement?I think the hips won't be an issue in the dress since its A-Line so it would be waist or bust.For example, Girl one is a size 20 based on bust but a size 24 based on waist. Her bust is the biggest measurement. Which size to order?Girl 2 is a 24 based on Bust and a 28 based on waist...but once again bust is the biggest.
