Grazia has alerted me kindly to these multi-coloured multi-strap heels from River Island.
Currently there are another two variations available online in blue and black, but I personally adore these purple, white and red versions. They have been lurking in Grazia's fashion cupboard for a few weeks, so if they're not at your local River Island keep checking back. They retail for £59.99
