Hello Ladies!
I really don't have too much to complain about here,  but I do have a small situation that I need some help with handling. 
My sister and I are both engaged, and both planning for next year. She has claimed June, and FI and I are looking at September. Her wedding will be in Texas (where her FI is from) and ours is in our home state, CT.
Now here's the issue. Everything I do, she compares to how she is doing it. I've been looking at BM dresses (early, I know, but it's going to take awhile to find them based on BM size differences and the fact that they're all scattered across the Eastern United States) Most of the dresses I've found have been in the $130-150 price range. None of my BMs have an issue with this price, except my sister. She keeps telling me how the dresses she's bought were only $30 for her BMs. Which they were, but they were also off a clearance rack at Belk. 
Our weddings are completely different styles, hers is going to be a much more casual "down home" type feel (they're using mason jars as centerpieces) Which is FINE, I hope no one gets me wrong here and thinks I'm bashing hers...but mine is going to be a much more formal affair.
That being said, I can't exactly find clearance dresses at a department store for it. I'm trying to be nice about the situation, I've told her that whatever she can't afford, I'll pay the extra above it, but she's being absolutely awful about them. It's almost like she's against wearing a dress that costs that much, even if she doesn't pay for it. She even went as far as to call me a bridezilla for making them wear them! I've asked every one of my other girls, and none of them have objected to the price. 
This isn't the only thing she's been obnoxious on though. She bashed the cost of my wedding dress compared to her own (hers was about 1/2 the price of mine). And she's been questioning me on the cost of all of the venues I look at. She's getting married at her FI church, which only charges $150 for the church and the reception hall for the entire day. My FI and I don't belong to a church, and don't have that kind of opportunity for a site. 
Quite honestly, I really don't think it's her place or that her opinion is warranted whatsoever. My FI and I are older than her, and established in our careers, and can afford more than she can. She and her FI are graduating from college 1 month before they get married, and can't afford the same that I can. This isn't a competition for me, to see who can spend more, but it seems to be for her, to see who can spend less. 
I've simply had it with her opinions and comments, and digs at how I'm planning things. How do I politely tell her to worry about her wedding and leave mine alone?
She's calling me the 'zilla, but honeslty, I feel like SHE is! I even avoid talking about weddings around my family, because I don't want her knowing anything I'm doing any longer, for fear that she's going to call me with another compairison. What do I do ladies??
