Kelly Osbourne fashion tips:

1. Invest in Spanx. The right underwear can make an outfit. It can smooth your shape or hold you in all the right places. Big knickers are not embarrassing - they're a bloody life saver! Don't follow the fashion trend of going knickerless and waving your ***** around. I think it's another form of addiction. It's an addiction to attention.

2. Always have a great pair of shoes in your wardrobe. Invest in an expensive pair. A good pair of heels. You wear a pair of Chanel shoes - no one would ever think that the rest of your outfit isn't Chanel and that it might be from Primark (a UK retail chain of very cheap clothes). Actually there is nothing wrong with Primark either.

3. I don't think you have to spend a lot of money on a bag. But pick one that shows off your personality. It's with you come rain or shine.

4. A great pair of jeans is really important. Find that one pair that you always feel good in. You can make jeans look fancy or you can them look casual. For me, the cheaper the jeans the better the fit. I get my jeans from Topshop and they only cost $80.

5. It's important to have a great bra. If your bra doesn't fit it can make you look fatter or saggy. Go to (a good underwear store) and get professionally fitted.

6. Don't wear spaghetti straps if your arms are not toned. It's not a good look.

7. Avoid flesh-coloured tights. They're just so old-fashioned.

8. Don't squeeze your body into a size smaller because you don't want to admit you're a 12 or 14. Wear the correct size for your body shape. Squeezing into a pair of pants that are a size too small will only make you have a muffin top.
