Cobalt blue is one of the very few colors I wear other than neutrals and I absolutely adore this sweater from Theory. I have worn it so much already this season that its already begun pilling and I just bought it last month. The pants are a must for any wardrobe and I know the price is steep but I got mine on the sale rack at the end of last season and I suggest keeping your eyes peeled on ebay or the sale rack. Nobody makes a better fitting and more flattering pair of leather leggings than Helmut Lang. They are so buttery soft and look good with basically anything from a silk tank to a cashmere sweater to a casual button down shirt. Needless to say they are one of the best purchases I have ever made.
