So my sister who is the maid of honor at my wedding bought a dress online. I gave each of the bridesmaids a navy blue color to match their dresses with. My sister picked a navy blue dress online and when it came in today it looked more black blue than navy. Am i the asshole for wanting her to return it and get another dress? She does have a limited budget and this dress was about $40 whereas the ones I'm looking at are $50- $100. I'm trying not to be a bridezilla because she is throwing me a wedding shower out of pocket but I dont want the color of the dress to look weird with the other navy blue dresses. Also if I'm NTA how do I ask her to change the dress nicely?
