This neutral SIR. Marne panelled asymmetric top is crafted from cotton and features a single shoulder strap, pleated details, ladder embellishment, asymmetric hem and a side zip fastening. The Marne is a river in the area of east Paris. The philosopher Heraclitus once said: 'You cannot step into the same river twice.' However we would suggest otherwise, as we've been wearing this SIR. top as often as is possible.
