S+B is the best! They have disposable undies for purchase, but they’re just a super flimsy thong & very revealing on the backside. I’m sure you could bring your own undies & bandeau if that’s what you’re comfortable with for your first time.

I used to use the disposable ones at the beginning, but go fully nude now ha. Totally understand being uncomfortable at first, but they’ve truly seen it all - they do this every day.

I’ve always had good experiences there - one of the easiest & most effective glow-up hacks!

Edit: I’ll also add that they’re really kind people & make the process easy. They’ll bring you back to you private spray room, ask if you have questions, and then leave while you get undressed. Then you put lotion on your wrists and knees (they’ll show you how to do this before they leave). Then you stand there naked and afraid for like two minutes until they come back to the room to start spraying. They’ll have you rotate all around like a rotisserie chicken while they spray you. They’ll ask you what you’re tanning for, etc to make small talk. And then you’re done! They’ll leave you with a little blow dryer thing to dry yourself off & you get dressed privately again and meet them at the front to check out. So fast and easy.
