Michelle Obama debuts London Fashion Week wardrobe makeover

The first lady has been seen in looks from Christopher Kane, Preen and Mary Katrantzou.

Michelle Obama is well known for championing up-and-coming designers and on a trip to London this week she took the opportunity to fly the flag for some London Fashion Week favourites.

It goes without saying that being first lady comes with some serious benefits - not least in the wardrobe department.

Obama was in town this week to promote the initiative Let Girls Learn and chose the occasion to debut an impressive selection of dresses from British-based design houses.

She landed on Monday without a trace of travel weariness in a bright yellow and blue lace dress by Preen.

Next on the schedule was a visit to the Mulberry School for girls for which Obama chose a black print dress from the pre-fall collection by Mary Katrantzou.

Finally for a visit to Number 10 to see the Prime Minister and Samantha Cameron, her most fashion forward choice yet - a black dress with floral patterns by Christopher Kane.

This isn't Obama's first foray with London designers; she hit headlines in 2011 when she attracted criticism for opting to wear a dress by Brit house Alexander McQueen for a White House State dinner, instead of championing a US brand.

But she hit back at the critics on Good Morning America:

"Look, women, wear what you love. That's all I can say. That's my motto."
