The bold blonde also displayed her eccentric sense of style by wearing a mix of loud pieces.

Betsey sported a sleeveless Patriotic blue blouse layered over a long black shirt and cropped black and white striped leggings.

She teamed those with a shiny blue long-sleeved shrug, a brown leather belt, and black sneakers.

Betsey was honoured with the Geoffrey Beene Lifetime Achievement Award, during the CFDA Fashion Awards in June, for her long-standing career as a designer of vibrant and whimsical clothing.

But her career wasn't always smooth sailing.

She bounced back after her eponymous brand was forced into bankruptcy in 2012 and is now a fashion force online.

Friday's collection remained true to Betsey's style, featuring multicoloured garments, loud prints, ruffles, and funky fashions.

Dressed to impress: She also posed up with model Ashley Smith and actress Jackie Cruz
