But Kelly Bensimon was a little more demure as she enjoyed a mother-daughter date at the 75th birthday of M&Ms in NYC on Monday. 

The 47-year-old reality television star shared her style with 15-year-old Thaddeus, as they both rocked all black ensembles on the red carpet.

The former Real Housewives of New York star illustrated her toned figure in skinny fit black jeans and a slinky grey T-shirt. 

She added a black blazer and showcased her golden tan in barely there leather sandals. 

The jewellery designer's glossy chestnut tresses were in a central parting and bouncing waves around her shoulders.

She flashed a big smile and appeared to keep her make-up to a minimum. 

Thaddeus rocked a mini-me version of her famous mum's outfit. 

The teen added high-top sneakers and carried a tan leather bag.
