This season, it's almost impossible not to fall for the underwater trend. What little girl didn't watch Ariel and want a mermaid tail and just who doesn't want to remind themselves of seaside holidays and swimming in clear blue seas every time they dress?

Certainly Charlotte Olympia knows just this and true to form she's created another covetable collection. It's the fresh green shell toed shoes that caught our eye. Olympia's created a luxurious yet wearable pair and injected a little je ne sais quoi with the quirky details. We love the mix of gold and the bright colour... though we'd still like that tail.

Anyone who keeps an eye on what's hot in the world of footwear will know that these Rupert Sanderson shoes for Osman are the sandal shape of choice right now.

Just take a look at the feet of editors, bloggers and stylists and you'll find that clean lined strappy sandals are always getting an airing. Sanderson created his minimal sandy coloured pair for Osman's SS12 runway to perfectly offset floaty lemon yellow dresses and smart electric blue trousers. He's since got us craving balmy summer nights to banish winter for good and give these beauts a spin.

Mermaids calling to fishermen, clams and coral, shells and the mysteries of the deep inspired designers for spring. And Chanel, with Florence Welch crooning from inside a giant oyster, led the way. But it's the shoes for spring from the fashion house that are getting some much deserved attention too.

With perspex heels having a moment and iridescent fabrics seen everywhere for spring this nifty pair combine both trends. Their shape and heel height have something reminiscent of those sandals loved in the '90s but are given delicate straps and fun textures for a more ladylike nod.

The disco's of the Mediterranean should see a lot of these beauties come summer.
