I think that Dj Suki is a good example to present two things: 1. Equality & 2. Modern Society.

1. Equality - because most famous Dj's we heard about are usually Men ( probably that's why some people still think that Female Dj's can't be as good as them - I heard & read opinions like that ) & Dj Suki is a Girl Dj - & she is Great! 

2. Some Troll girls are wearing dresses or skirts - & she's wearing a top & trousers - so as we can see there is no one dress code for girls in Troll Village: they don't have to wear dresses there, they can wear What they Want! - just like in a modern society ( All girls had to wear dresses in the past in human societies - but now we can choose between dresses or trousers, whatever we like more! - & TBH Thanks God for this - I personally don't like to wear dresses, I prefer My Jeans - & I know many girls like this ). 

And one more thing to complete Dj Suki's 'Modern Look' is the jewel on her belly - she looks like a modern girl with belly piercing or something like this! :) 💎 - the other Trolls I saw don't have it.
