It's annoying when a 12 year old has a better wardrobe than you.

We're obsessed with this adorable video in which Mad Men's Kiernan Shipka (Sally Draper) takes Laura Brown through her wardrobe. With the likes of Oscar de la Renta and Marc Jacobs on her rails (not to mention Chanel on her feet) this 12 year old starlet already has a better wardrobe than most of us will ever have.

She also appears to have a real sense of humour, pulling out one embroidered coat made from haberdashery fabric, describing it as "my Sound of Music Coat", and confessing she loves Willow Smith's look but wouldn't try it for fear of looking "like a clown".

We also learn she's a fan of American Rag (for Toms and petticoats) and Converse hi-tops.

We found the cute Little Marc blouse Kiernan wears in the video for sale online. Go on, treat the kid in your life (or give it a go if you're a particularly tiny adult). Kiernan apparently teams it with a cardigan to enhance the 'peter pan collar, printed vibe'.
