First of all, top of the evening to everyone

I'm going to bed, so this will be a post-and-run, but I'll come back first thing tomorrow.
CN: 4 BMs love the dress I posted last week. Last BM has been slightly snarky since I didn't choose her as MOH. Angry that I want to go with this (cheaper) dress as opposed to a more straight-laced, bridesmaid-y style. WWYD? Go ahead with the dress and maybe make her mad? Forget picking out one dress and have them wear whatever? Did you make an executive decision as a bride? I love this dress, and I wish everyone could wear it, but I don't want to create hurt feelings or drama.
Details: I've gone BM dress shopping independently with four of the BMs (two are located in CA, two are located in IL). Had a possible dress that the two in IL loved and the other three were meh about. Four BMs LOVED new Anthropologie dress I foundt, want the green light to buy it.
The last BM is a childhood friend of mine who was hurt when I didn't choose her as my MOH. I think she's still bummed, since there have been some uncharacteristically snarky remarks popping up (all about my MOH and her being a "lowly" BM). We talked it over, but it's still sort of weird.
She freaked out when I showed her the dress and said it wasn't formal enough for a wedding (it's at a wine bar, urban-vintage style, pretty casual). She knows that my MOH helped me find the dress, and I'm worried this might be behind some of the negative reaction.
Do I just pick the dress that I love, knowing that she'll be unhappy I didn't pick her first choice? I really do love the dress, and the other four BMs are very much on board. I know that I don't have to have them in matching dresses, but I really would love to make this dress happen. WWYD?
Thanks for taking the time to read!
