This blue Saint Laurent denim ruffle bib shirt is crafted from cotton in Japan. Featuring a stonewashed hue, this top has a rounded hem and high ruffled neck, ruffles around the cuffs and black shiny press stud buttons down the front. 'Bib' stems from the old verb 'bibben', to drink, either because it was worn while drinking or soaked up spills. Spill on our Saint Laurent? As if.
