<human>: Can you provide a brief overview of the text?

Ok, I've been chosen to stand up in my best friend (of 12yrs) wedding. I was runner up, but after a fight with her sister I'm now maid of honor. I would be thrilled except that she's turned into a controlling crazy bride. 

NOTHING can be requested, discussed, etc. It's all her way or no way. Even down to each bridesmaid HAVING to wear different dresses (different straps, cut, length, etc) matching colors. Which is fine, it's just a hassle when  you're trying to order dresses 3 months before the wedding. THEN she chose our hair dos - this would be fine if she didn't choose a hair do that makes me look like a blimp head. Then there's shoes, jewelry, hair do appointments, make up, etc. She knows we're (bridesmaids) are all struggling to scrape up the extra money to make her happy. However, she isn't taking that into consideration. EVERYTHING must be perfect. 

And yes, her and her hubby-to-be (my cousin) aren't even officially engaged yet. No rings. But the date is already set for Oct. 21st. ARE YOU KIDDING ME?! Anywho.....

After trying to give her ideas on hair dos that would be more flattering for my frame....she straight shot them down. =( 
Then the dress color battle. She tried to get 3 very pale girls in 3 very vibrant yellow dresses. Thankfully she chose to go with navy blue after all 3 of us thought it was terrible. 

That's just what happened yesterday/ongoing today. There is so much going on and so much drama because of the shotgunning that I don't know how to stop her from making us feel like shit. 

How do I tell her I prefer a different hair style? How do I tell her I can't afford to pay for all the extras (especially when I can do it myself)? 

**THANK YOU REDDIT
<bot>: I'm my best friend's maid of honor, she's bridezilla in the making. How do I approach the subject of not agreeing with her without having her blow up?
