AITA for asking moms friend to pay for my new clothes after my mom's wedding ruined all my good clothes?

Hi. <br><br>I am 16 and my mom just got married. My stepdad has money and he paid for the wedding and all of the guest's hotel, food, etc. My mom decided on the most cutest girl in our school to be her bridesmaid. I'm not the type of person to argue or be jealous, but I was pretty sad my sister came to the wedding instead. <br><br>My mom's bridesmaid and I aren't close, but she's really nice and I like her. My mom invited her over a lot to plan the wedding, and she would usually bring me snacks when my mom wasn't around. So I came to accept my role. <br><br>The wedding was beach themed. My mom spent a lot of money on my bridesmaid dress, which was good because I was a size 0 before. I started losing weight from stress and I was a size 4 by the time the wedding came, so my new size 4 dresses were a little too tight. I thought it would be fine though, it's only a couple inches. <br><br>The wedding day came. I looked nice. My mom did my hair and makeup really well and I felt great. I got into my dress and it was ripping in one of the seams already, so my maid of honor fixed it temporarily with some tape, and it stayed that way the whole day. I was just happy to not notice it too much. <br><br>That was fine. The issue came when we went swimming after and my dress got all soggy, then my cousin tried to dry it with a blow dryer, but that made it get all wrinkled too. The day was over after that. I had no good clothes left. I spent the night in my grandparents' basement. My mom took me shopping the next day and I got some new things.<br><br>My mom's bridesmaid comes over tonight, and she usually stays over when my mom is busy. I asked my mom if it was ok if she slept over and helped me clean my room. My mom said it was fine, and my mom's bridesmaid said that she wanted to help pay for my new clothes since she caused me to lose all my good clothes. <br><br>I started getting really mad. I told her to get out and never come back, that I obviously didn't want her near me. My mom told me to calm down and to tell her bridesmaid that she didn't have to. <br><br>I told her that she did. She ruined all my good clothes and I said nasty things to my mom's bridesmaid. My mom is in her room. I guess I might be an asshole.
