I think it's part of the false reality they like to create for themselves, believing that their subscribers are mixed with men and women that are legitimately invested in their lives beyond the superficial. "Influencers" are just sales people and all these IG girls doing this half-assed OF content delude themselves into thinking they aren't sex workers since they don't sell hardcore content. Natalie is milking it for all she can since she's more likely to pull the plug than do hardcore stuff anyway.
They can write off the outfits that they feature in videos. Just like the travel YT'ers can write off a lot of their travel expenses, these chicks can write off their try-on hauls. Plus it's a simple gimmick for a video, and lots of folks probably do like watching her change.
