Any hairdressers want to help me with a step by step?

Anyone want to help me get this kind of style? It's from the Selling Sunset lass, also seen Khloe Kardashian rock it very well.
I'm not quite as glam as that lot BUT I have the exact same shade and length hair and I feel like it might make a nice change? Should be quite straightforward too??
As long as it doesn't look like an oil slick

I'm not a hairdresser but is it not just a load of gel on the sides, poss held in place by kirby grips behind the top part? Not sure how the top part is combed back & doesn't look gelled - unless it's hairspray?
