Bridesmaids

Would you expect a bridesmaid to ask if you cared if they dyed their hair a crazy color days before the wedding? I thought of this when I was watching Jersey Shore and it was mikes wedding and Jwoww showed up with bright red hair the day of the wedding and it looked amazing. At the time I thought Jenni was a bridesmaid but she wasn’t. But I started thinking if It was respectful or like didn’t matter if a bridesmaid dyed their hair crazy because of like pictures and stuff idk what do you guys think?
