Woman Not Allowed in Brother's Wedding Party

A woman felt sad after being kicked out of her brother's wedding party because she is 'too large' after having three kids. Her brother first asked all his sisters to be bridesmaids when he got engaged.
The woman said her brother was very close to his sisters and was excited to tell them they would be bridesmaids. He told them how excited he was when they helped him with his proposal.
The family is Mormon and will have a small temple ceremony before a bigger reception. But about a month after the engagement, the woman thought something had changed.
The woman asked who would be bridesmaids and groomsmen after her brother shared the wedding colors.
He did not answer her question. She later found out that only one of her sisters was chosen as a bridesmaid.
The woman was initially disappointed but understood it was the couple's decision. Things got worse when her sister showed her a private message from the bride.
The message said the woman was not part of the wedding because she is 'too large'. She had gained 15lbs after having her third child six months ago.
The woman's other sister was not part of the wedding because of her piercings.
The comments hurt the woman's feelings. She was also hurt that her brother did not tell her she was not part of the wedding.
The woman and her sister do not 'look' good enough for the wedding party.
The woman found out that the color palette was not just for the wedding party.
Every guest had to follow a strict dress code, including children.
The woman had to buy new clothes that fit into three approved colors for her, her husband, and their three children.
The woman is not part of the wedding but has to buy new clothes for her family.
The woman thinks it is crazy how weddings have become so focused on looks.
