Snap up a (mock) Crocodile tote in royal blue

If you've got around $30,000 to spare and you want to spend it on a bag... (car? mortgage? nah...) then why not splurge on a Celine crocodile trapeze tote in royal blue? Kate Upton has done just that and has been seen with this covetable bag on her arm all over town... and for months now. She's sure getting her money's worth.

Happily, there are less expensive versions of this iconic Celine bag available in mock croc, which would set you back more like $3000 - kinder to your wallet and to the poor old crocodiles.

Kate isn't the only celebrity to succumb to this chic French brand's charms; Olivia Palermo, Alessandra Ambrosio and Lucy Liu are all fans of a Celine tote but even their mock versions are a bit pricey for most of us. So head to the high street where you'll find some much more affordable options for sale.

Just think of all the crocodiles you'll be saving.
