Teen stars appear to be ruling the red carpet this week.

‘Mad Men’ star Kiernan Shipka joined January Jones at PaleyFest in Beverly Hills, California, yesterday.

She looked super cute wearing an Oscar de la Renta Spring 2012 floral-print party dress from the childrenswear department, which debuts this month.

Her floral-burst dress was teamed with simple nude pumps, wavy hair and glossy lips.

What a great way to show off your first Oscar dress. She’ll be a fan for life now.

The Spring/Summer 2012 Childrenswear Collection will be available on www.oscardelarenta.com Thursday, March 22.

The playground is about to get a whole lot chicer on the Upper East side.
