Am I wrong

For being annoyed that my wedding is in 4 weeks and my bridesmaids don’t even have their dresses yet. My maid of honor wants to look perfect and my sister wanted me to pay for her dress because she doesn’t have $30. Am i wrong for being annoyed they wanted me to lose a days worth of pay from work to attend the bachelorette party they are hosting for me. Why didn’t they do it on my day off? All the men are ready to go. I haven’t ask my bridesmaids to do anything but 1 task and that was to pick their dresses and purchase them.

*Lisa I asked my bridesmaids via proposal box if they would like to be in the wedding party. 1 is my sister and the other is my best friend of 20+ years. They post on social media all the time about $100 worth of makeup that they buy but can’t spend $30 on a dress for me? I gave them months notice and I said pick a long black dress. They had free range to get whatever they liked so they could reuse the dresses and spend the amount they could afford. I say $30 because I found affordable dresses as a suggestion in that price range.
