Fergie seems to love her J Brand 901 denim leggings! She has worn them in the Pitch wash twice and she owns the Viper wash and the Blue Viper wash! They look gorgeous on her! I think J Brand, Paige Premium and Charley 5.0 are the leaders in denim leggings so far! There are so many choices to choose from but these 3 brands seem to be a celeb favrouite!
