As first seen on blog "The Wardrobe of Ms. B" here: Grey tweed
She is wearing tights similar here: WOLFORD MATTE OPAQUE 80 DENIER TIGHTS
Set of two Matte Opaque 80 denier tights, Wolford's 80 denier black opaque tights have a flattering matte finish. A soft knitted waistband and a touch of cotton and plenty of stretch make them comfortable as well as practical. This pack of two will see you through the working week.
