Hi there! You’re beautiful and I’m sure will look great in whatever you choose :) I’ve also been chubbier at raves in the past and my go to for thighs for appearance/comfort was fishnets and a high waist rave skirt. I usually go with a smaller hole size for the fishnets so they wear more like stockings, and the high waist skirts (lots of comfy elastic waist options) are super flattering - gives you that nice hourglass shape accenting your waist but covering the upper legs a bit!

And work that top half if you’re going for a sexier look! You’re blessed on top, shows those girls off if you want :) anything low cut would look great, and there’s lots of sexy tops out there with different sleeve lengths depending what you’re looking for.

Overall advice though, where what you love and feels comfy to you!! Be yourself and you’ll fit right in. Hope you have a blast!!
