Only Britney Spears is capable of taking several fashion no-no's and rolling them into the one outfit.

The singer, notorious for blatantly shunning the advice of stylists, revealed another display of her poor fashion sense today when she stepped out in a see-through nightie-style dress, trilby hat and ugg boots.

To make matters worse, she unwisely chose bright red underwear which could clearly be seen through the poorly-fitting dress.

Spears, 28, stepped out in Beverly Hills for a spot of shopping as it was revealed she is the first Twitter follower to amass five million followers.

Despite the fact most of her 'tweets' on the social networking site come from her management team, Spears' popularity has seen her beat popular tweeters Ashton Kutcher and Lady GaGa to the milestone.

Spears has another reason to celebrate after it was revealed this week she had sacked her manager Jason Trawick so they could pursue their blossoming romance.

The couple were first linked two years ago, but have had an on-off relationship.

They chose to stop working together to allow their romance the best chance of success, perhaps thinking of the old adage 'never mix business with pleasure'.
