It's eyes and interest on your product, isn't it? Doesn't have to be about things available to buy.
But if your product is only things to buy, which this is, then not actually seeing any of the product isn't that helpful, surely? I couldn't tell you if it was a homeware line she'd collaborated on, a kids range, an adults range, underwear, perfume, makeup, all of which Next sell. I'm assuming this is one part of a larger media campaign around her collaboration, so maybe they don't need or expect lots of exposure from it.
Just seems a bit pointless to tell us you're going to the event, post about who else from the gram is there and how pretty your place setting is and then not actually show us any of the content that you saw there.
Ah, fuck it, I'm massively overthinking it.
