US presidential couple, Donald and Melania Trump, undertook a four-day state visit to Tokyo, Japan on Friday and the trip proved the perfect opportunity for the First Lady to really flex her sartorial muscles.

The 49-year-old made sure to pack a number of high fashion outfits and delivered an estimated £10,000 worth of headline-worthy dresses in the past 48 hours alone.

To kick-start the fashionable proceedings, Trump wore a Calvin Klein shirt dress emblazoned with old postcards of the American West on the flight out - a not-so-subtle tribute to US culture - which retails at $3,900 (approximately £3,079).

To finish the breezy ensemble, she wore a pair of navy Christian Louboutin pumps.

Further cementing her status as a global fashion muse, Trump chose a £5,847 Carolina Herrera midi dress for an outing with the prime minister’s wife Akie Abe on Sunday.

Further proving the ‘Melania Effect’ is very real, the ensemble soon garnered sell-out status with a number of social media users praising the look.

I do love this dress by Carolina Herrera worn by first lady Melania Trump in Japan. Plus I think this postcard dress by Calvin Klein is so cute, crisp and summery looking. Perfect dress to wear leaving on the trip to Japan. #MelaniaTrump #firstlady pic.twitter.com/0HiT8QOz16 — Karen Callahan (@CallahanKaren) May 27, 2019
