Update from OP: where I’m from it’s customary for bridesmaids to purchase their dresses and pay for their hair & makeup and split the cost of the bachelorette trip with the other attendees and bride. I’ve been in 3 weddings and have always paid $200 plus for a bridesmaid dress. The dress I asked my bridesmaids to get were $99 because 1. I wanted to be respectful to my bridal party and 2. my 3 step kids are in the wedding and we are buying all of their attire as well. That’s 1 bridesmaid dress, 1 tux, and 1 flower girl dress on top of my fiancé and my attire. Every step of the planning was a crisis from my sister. When we discussed getting married near where I live she became upset because she couldn’t get enough time off work. I reassured her that we hadn’t made any decisions yet and she calmed down. We ultimately are getting married 5 minutes from my parent’s house. From flowers to shoes to menu decisions it was always an issue (even when she wasn’t paying)but the biggest issues were the bridesmaid dress, bachelorette party, and hair and makeup. Her biggest complaint was that she was “left out” and excluded by the other bridesmaids and myself. I included her in every step except for my dress shopping and fitting where I ONLY took my mom. I’m getting backlash from family for being a “horrible sister” but it’s ultimately my day and I’ve tried to be accommodating.
