Cat Deeley is so kind and thoughtful, she set about giving us a handy three-step lesson in designer shopping etiquette in LA this weekend.
It goes something like this:
1) Look pretty and smart, but not too try-hard.
2) Wear glamorous flats instead of heels to ensure maximum shopping hours.
3) Finally, and most importantly, rope a cute shop assistant/minder into carrying your hefty shopping haul for you.
Job done nicely, thank you very much.
