We’re not sure about… Famous nails

Celebrity collaborations for charity are one thing, pointless cash-ins are another. The latest is from Lily Allen, who has collaborated with Elegant Touch on a range of stick-on nails, named after her songs. Hard out here, indeed.

From £6.99, eleganttouch.com

We’re buying… Hats off

It’s that time of year again when you start having to consider cold-weather accessories. This season, The Kooples has teamed up with Art Comes First to launch a line of hats – unisex of course, so that you can share your headgear with your other half.

From £195, thekooples.co.uk

We can’t wait for… Denim swag

We’re saving up for… Blade runner

If you’ve already starting thinking about what to wear to Christmas parties, Casadei has just released a re-working of its famous Blade shoe. The Mini Blade has been reinterpreted into a sandal style, with the same famous steel heel, in black, gold or red.
