We know that pretty much everything she says is a lie.
She wanted things from Hermes for whatever reason - maybe to up her 'lux' profile, no idea.
She bought the cheapest thing she could from Hermes - being a belt. You couldn't see her in any of the jewellery and she's not going to drop a few grand on a purse is she?
Then she buys the boots from Sellier - we see them on their instagram feed.
Something then happens - either she gets Carrie to do a deal for promotion with Sellier, or she sees the Birkin and approaches them for a promotion/voucher, who knows or cares, but she's bought a bag from them, not the bag she really wants, and has paid over the odds for it, when she could easily have got the black Kelly for half what she paid for this.
No doubt it will disappear from her closet after a few photo shoots, just like everything else does. The sage Lady Dior vanished, doubt we will see the tan Mulberry she bought a few weeks ago, all the cashmere N Peal and other make jumpers she unboxed in the autumn have never been seen, and she's walking around in Nasty Gal knitwear.
She's the only influencer i watch who never sets foot in Zara to buy normal day to day staple pieces - is that because she'd actually have to pay for them, no discount, no voucher. I mean she doesn't even buy from Topshop either. Just freebies from NastyGal, Boohoo, Karen Millen etc,
It is all smoke and mirrors always with Lydia, don't forget how she conned us with the Hermes boots and so many other things in the past.
