Taylor Swift's influence can do wonders for a small business… Conclusion Beauty happily learned this was true after the singer wore her brand to an NFL game.

Co-Founder Aliett Buttelman tells TMZ … she's always been determined to show off some sparkly freckles on the pop star following the launch of Conclusion Beauty in May. According to Aliett, she felt the trend matched Taylor's mood on the Eras tour… which features the chart-topper in a number of sparkly outfits.

To get the glittery freckles in Taylor's makeup bag, Aliett confessed to sending a PR package to the agency that represents the pop star's makeup artist. However, Aliett isn't 100% sure that's how they got on Taylor's radar… and cites a few viral TikToks and Instagram posts as other possibilities.

Not to mention, Conclusion Beauty also sent its Red Team Spirit Speckles to several Kansas City Chiefs WAGs… so Taylor could have easily seen others decked out in glitter and jumped on the trend.

Regardless of how she achieved the bejeweled look, Aliett confirms that the Grammy winner wore the brand's Gold Stardust Speckle Makeup Patches cheer on Friend Travis Kelce during Monday night's game at Arrowhead Stadium.

Good news for Conclusion Beauty: Swifties are already looking for the product… Aliett told us that sales were up 2,500% in the last 15 hours.

The increase in sales is accompanied by a massive increase in website traffic… a clear sign of Taylor's influence.

Understandably, the newfound attention on her website feels “incredible” to the co-founder… and her team is now working “around the clock to keep up with demand.”

Aliett also tearfully responded to Taylor's subtle support, wiping away tears of joy in a viral TikTok shared Monday night.
