Victoria Beckham is "inspiring" to work with, according to accessories designer Katie Hillier.

The former Spice Girl-turned-fashion designer has teamed up with Katie to work on her highly-praised handbag line and she has impressed her co-worker with how good she is.

Katie said: "Collaborating in her Battersea office is like working with your best friend. She's focused and inspiring."

Katie - who started work at Luella and is behind Marc by Marc Jacobs' accessories - has previously insisted Victoria is involved in every process of the handbags and is always giving useful and practical advice.

She said: "She designs the bags. At the start of the season, Victoria gives me a huge folder full of all the stuff she's seen that she likes, and we work through it together. Often I'll come back with an idea and she'll say no - she's particularly picky about fabrics, which is unusual. Lots of people I've worked with are like, 'It looks good - great!', but Victoria will lick her finger and wipe it on the cloth and be like 'Uh-oh, I can see what's going to happen to that in The Rain!"

"She wear-tests all the bags when they're in development, taking them everywhere she goes. All the bags are designed to fit into her life and that's why they just work."
