Me Too by Meghan Trainor is on Just Dance Summer Party 2
During The beginning the dancer wears a big puffy dress with some plastic veins around it. Starting at the second time the chorus is heard her dress drops revealing a thin black outfit. She is see-through in certain parts and you can see the background.
Gold Move 1 is where you put your arm in the air and lift your leg up. Gold Move 2 is the same thing but you also pump your arm.
The background is a city.
