I have something v similar to this or I have the green dress at the top with swirly lines to wear with opaque black tights and black booties.
Love the green dress but scared of being cold and haven't got anything except a dull ms black cardi to put over it. I have a slightly elderly gold lame cardigan that might work (wish I had somehting to replace it!)
Accessories for the green dress will be gold earriings and a gold cuff bracelet.
the brown dress will be much warmer obv but would need a bit of last minute strategy on the accessories and shoes.
