It's been a few years since she really splurged apparently
I think we have different ideas of a splurge! A quick scan of her recent videos shows her buying;
Nintendo Switch before Christmas
LV purse last year
LV card holder last year (IIRC it was returned)
Mini Pochette a year ago
2 Rebecca Minkoff bags just over a year ago
Phillip Lim bag just over a year ago
I seem to remember a Mulberry bag too
It's absolutely everyone's own business what they choose to spend their money on, but pretending that you haven't treated yourself to a 'big purchase' for years when you've been consistently buying things is a bit odd. Unless these things genuinely aren't considered as expensive to her.
