First it was The Row who presented a 29000 euros crocodile backpack that sold out almost immediately, then many designers have followed the Olsen twins and this season the runway was flooded by backpacks. They come in every size, colour, and texture possible so there won't be a problem for you to choose one.They are cool, practical and super trendy.

Put some big bunny ears and a fluffy cotton tail on your iPhone. Rabito's iPhone 4 bunny cases are so funny. I just saw them in Harrods, where they are sold exclusively here in the UK, and they are fabulous. I dare you to walk around with one of this. £19,95 http://www.heyrabito.com/rabito

I'm not obsessed by the Hamptons but there are some beautiful houses out there. Just check Anna Wintour's beach house. It's an absolute gem.

Famed french bakery - Poilâne- has recently opened an all-day café in Cadogan Gardens, just off Sloane Square. They have already a small bakery in Elizabeth Street, but the buzz about their famous biscuits (punitions), bread and croissants was so big that they've decided to expand and open a restaurant too. Great idea as it is packed every single day. The food here is utterly delicious and surprisingly informal. Tartines - open-face sandwiches are prepared to order at the counter in front of you, served hot, and you can even eat them with your fingers. The menu includes other classic french dishes, plus amazing pastries and freshly baked bread. You can also take home with you biscuits, bread and pastries but that I try not to do as it is already difficult to resist every morning Poilâne's bakery across the street, here in Elizabeth street. 39 Cadogan Gardens.

Hello everyone: here are my top five nail polish trends for 2012. I'll try them all.

1. Sparkling nails. It sounds tacky but i'm dying to put some glitter on my nails and make them shine for Spring. Fierce!

2.Metallic. If you can't do glitter, then do metallic. Chanel was the great responsible for this trend.

3. Neutral, like sand, stone, granite and bone tones. Love it.

4. Bright colours. Red, blue, yellow...as long as it's a bold colour, you can wear it.

5.Ombre. First it was the ombre hair trend, then it passed on to clothes and now ombre has arrived in the nail polish world. It's not an easy trend to follow, though.

Chanel arrivals: Paris Fashion Week Haute Couture. Vanessa Paradis (1); Ines de la Fressange (2); Daphne Guiness (3), Alice Dellal (4); Cameron Diaz (5); Anna Wintour (6)
