Bridesmaid rant

Hey y'all! So recently I sent my bridesmaids the link to azazie.com and let them choose their own dresses as long as they were burgundy and long. I figured this would be the easiest way to let them choose a dress they actually like, but also have the exact same color. Also it's a lot easier since they are all from different parts of the country and wouldn't be able to meet to try on dresses. Today, one of my bridesmaids text me and said she doesn't want to order a dress offline because she doesn't know if it will fit, and said she wasn't going to order one from there, but was going to go to David’s bridal instead. I tried to explain that azazie let's you sample a dress for $10 to see if it fits right, but she says she wants to go to David’s bridal. Then pinned it back on me saying I chose a site that only had basic sizes. Which she is..(They do custom as well) I don't know what the deal is...All I want is the colors to match.I didn't think I was being to unreasonable. Rant over.
