Lauren Conrad plans to wear ''head-to-toe'' denim this season.

The reality star-turned-fashion designer thinks the statement look can work well if the shades of denim do not match and are accessorised carefully.

She said: ''Double up on denim. Some may refer to this look as a 'denim sandwich,' but I think head-to-toe denim is a definite do for fall. Just be careful not to mix two like-coloured pieces. Ideally you want contrasting shades - like a super light denim (or chambray) top and dark denim bottoms. To give the look a girly touch, add a brightly coloured statement necklace.''

Although the weather may be changing, Lauren insists the colder months don't mean a complete wardrobe change is necessary.

Writing on her website, she advised: ''Add a cardigan. Transition your summer styles by topping them off with an oversize cardigan and closed-toe shoes (or sandals if it is still warm in your town).

''Personally, I love the feel of a 'boyfriend'cardigan since it feels more relaxed and the oversize silhouette is cozy for fall.

''Transition your sundress by layering over a lightweight sweater and pairing the look with low-rise booties.''
