Check out vendors at shows. Some of the best stuff can be found there.

Neo4ic.com is the shit. MDNT:45 & kutzarov designs looks hella good too.

Bohemian/burner fashion can get expensive, it looks really good though. Yoshi Zen is a personal favorite of mine.

Cardigan & matching Harem Pants is an easy fit to do under $60.

I also like these ponchos as wearable art.

I have this set from Threaded Roots that I enjoy.

You can find great items on Shein if you look.

The right accessory will turn heads. https://coquetryclothing.com/ also makes great hoods.

Badinka & CandyCatz make male bodysuits that look great.

You can be anything at a rave. Just a plain T and shorts is fine. Or a mankini. The number of looks is infinite just pick the one that you feel most comfortable with- the one that reflects you is what likely will be best.
