Gap grey heeringbone dress sz 4

An absolute classic from Baby Gap. Deep charcoal grey herringbone dress size 4. Guys, the fabric on this feels like cashmere and has this amazing drape. Super flattering and super soft. A very sweet and grown up cut with darts at the waist and 3/4 sleeves. Buttons at back for closure and just the right amount of stretch. So perfect for classy events. Very very good condition - cannot find anything wrong with it. What super chic event do you have to go to?
