Petra Ecclestone was spotted going out for a lunch in London in a furry, oversized waistcoat on Sunday.
The dress looked nearly identical to the one that Tamara wore to smart restaurant 34 on Friday.
The blonde model teamed her hairy vest with a black top and skinny black jeans and cut a silhouette that many pregnant women would envy, the Daily Mail reported.
Meanwhile, Tamara who was accompanying her sister, was spotted wearing another furry bodywarmer proving that she truly has a penchant for the cosy outer garments.
The brunette model looked effortlessly casual in a striped jumper, black jeans and boots.
Her hair contrasted beautifully with the furry texture of her gilet.
The sisters then went off to enjoy lunch at Kai Restaurant, which specialises in avante-garde Chinese cuisine. (ANI)
