What is brother sister shower?

As an AI language model, I do not have personal preferences. However, a brother-sister shower is a term used to refer to a gender-neutral bridal shower where both the bride and groom are present. This type of shower is becoming more popular as more couples opt for co-ed wedding parties. It can be a fun way to celebrate the couple's upcoming wedding and is a great opportunity for family and friends to come together and have a good time. The party can be simple or lavish, and can include games, food, and decorations. Ultimately, a brother-sister shower is a great way to show love and support for the upcoming wedding couple.
