The narrative of most girl bands is having fun with friends. In the Destiny's Child and Little Mix video they did this by showing them having fun and hanging out in a room, whereas the spice girls were going out causing chaos.
The themes of some girl band songs tend to be about the idea that friends are more important than men.
Locations varied from outside to inside depending on the type of song. Ballads tend to be outside like in the Spice Girls 2 Become 1 video. While most upbeat songs where filmed inside like Little mix's How Ya Doing.
Destiny's Child and the Spice Girls where seen more for male gaze with their clothes, in Destiny's Child Cater 2 U they are first shown not wearing any clothes then they are shown not wearing much clothes e.g bikini or short skirt. Little Mix however are for the younger generation and don't wear provocative clothes.
Girl bands tend to have their own personal style in what they wear but not too much of a difference to showthat their a group. The costumes also depend on the type of song as well. For example, if they are singing a
ballad they tend to wear dresses, whilst rock song tends to have an edgier look.
