DOTING DAD: Following up his beautiful gown laden runway show on Tuesday night, Oscar de la Renta showed his spring Summer 2013 childrenswear collection at his studio Wednesday. The runway was full of adorable little girls in mini versions of Oscar’s gowns such as a pink tulle tiered number that was almost identical to an aqua version shown on the big girls as well as plenty of chic play wear and sundresses. Not to be outdone by sissy, there were also plenty of boys looks which were the classic styles that well-heeled types adore; blazers, oxfords and chinos. The designer watched the show from the sidelines like a proud Papa and took the bow with his vice president, design director Catherine Monteiro de Barros.
