A bridal shower is thrown in honor of the bride, so the hosts get to plan it. The hosts are usually the bridesmaids and one or both moms.
It is not uncommon for a bride to share some ideas with her mom and bridesmaids as to what she may want or not want at her shower but I wouldn’t recommend a bride planning the whole thing and then send the bill to her ‘maids.
If you have strong feelings about certain details, especially things you don’t want, it’s okay to share that information. But since the event, many times a surprise, is planned and paid for by others - who I’m assuming will enjoy planning this very special day - I’d let your bridesmaids and the moms take the lead and the bride should sit back, relax and enjoy it. After all, there are plenty of other things on your to-do list.
