When going to a rave you need things that are loose fitting and allow you to move with the energy. You should avoid items that make you think make you look hot and rather go with things that make you comfortable. Another important part of the way you dress is the colours you choose to wear. Raves have a lot of lights and colours. People usually want to have different looking clothes with bright colours that stand out.
