Losing friends during wedding planning.

Yes I lost two friends of ten years. It all started because I said I wanted all the bridesmaids in the same dress. Only one bridesmaid was upset about this (one of my friends). Everyone else family, didn't care and said they would wear whatever I wanted, so I let her pick the dress as long as it would still be flattering for the others. I want all of my ladies to look and feel great. She is a bit bougey and likes tight fitting flashy dresses. He response was well I'll pick one that I'm sure no one else can afford. I said I'm sure we can find something beautiful $200 or less. She sent me examples like skin tight mermaid dresses (my sister is plus size) and others with trains on them. I told her i didn't want form fitting or the same neckline(sweetheart strapless) as my dress and Seibert not trains. She says I'm micromanaging being a bi#%$ and a bridezilla, and doesn't like that i want everyone in a plain bridesmaid dress. Uncalled for to talk to me like that but i let it slide. I never said plain but Damm I am never flashy and this is my day to shine. My sister is the same size as me and when i tried the dress on i looked like a stuffed sausage lol. My sister would have still worn that but i would never do that to anyone. So she picks the dress everyone else buys the dress before the deadline. Then 5 days before the deadline she says she wants to wait to buy the dress 3 months before the wedding ( even though she knows the consultant said it can take up to 5 months for dresses to arrive) because she doesn't want to pay for alterations she is a body builder and is planning to drop 2 sizes. I swear she stressed me out so much I thought I was being very accommodating. My fiancé ended up sending her a message that his cousin will take her place because he doesn't like how disrespectful she is being to me. Then my other friend defends the one who was disrespectful. Said that I need just need to let some things go, like don't be picky about the bridesmaids dresses. They both ultimately start ignoring me and ends or friendship
