'First Teens' become style queens

US First Lady Michelle Obama, accompanied by daughters Sasha and Malia on a visit to London on Tuesday, announced a new partnership between the United States and United Kingdom to improve girls' access to education around the world.

Malia, 16, and Sasha Obama, 14, have blossomed to become smart style queens who graced the city's Downing Street, since their last visit in 2013.

The First Daughters, looking elegant, poised and confident, appear the epitome of well brought up young ladies.

Almost overtaking their mother Michelle's towering frame, the pair has shown just how much they've grown up with the wardrobe transformation in just two years evident, from hoodies and trainers to feminine dresses.
