Larissa showed off her new look, inspired by Kylie, last week with a one-hour lingerie show on the webcam app, CamSoda ... and we've learned those 60 little minutes hauled in more than $100,000 for the site.

Our sources tell us Larissa's show hit the six-figure mark thanks to people paying to view the sultry show and tipping ... and we're told she had 10 times the number of viewers CamSoda usually sees for the biggest XXX stars and Instagram hotties who host.

It's pretty impressive ... we're told Larissa's show had so much interest, it now ranks in the Top 5 all-time on CamSoda. Hat tip to Kylie!

As we first told you ... Larissa dropped a cool $72,000 for a bunch of cosmetic surgeries, going under the knife with Dr. Lane Smith in Sin City to try and come out looking like Kylie.

Larissa got a boob job, liposuction on her abs and waist and a fat transfer to her bottom ... plus botox, fillers and laser facials. The whole shebang, ya might say.

The people have spoken ... and it definitely pays to be a Kylie lookalike.
