Gwen Stefani denim blonde sunglasses saggy pants Leave this look to Justin Bieber, Gwennie!

We caught up with Gwen Stefani on a stroll through LA today, and the singer either forgot her belt, or was trying to make a fashion statement. Either way, this is a major fashion DON'T!

The "No Doubt" frontwoman paired her sagging jeans with a striped top and grey sneakers, and thank goodness she opted to carry her bright pink leather jacket, or else it would have been icing on the cake of this fashion felony!

The only redeeming part of this ensemble is the blonde beauty's fab abs!
