Melania Trump masters the art of casual style in $695 Calvin Klein shirt

Melania Trump has mastered the art of casual Sunday attire.

The first lady exited Marine One after a weekend at Camp David in a stylish, but pricey, ensemble -- a red Calvin Klein button-down shirt with two beige pockets on the breasts. She paired the eye-catching top with a pair of black J. Brand trousers, a combination that truly showcased her enviable curves.

Melania completed the rest of her look with accessories from Christian Louboutin, Hermès, and Saint Laurent.

Melania and President Trump appeared to be in good spirits after their relaxing weekend away.

While the first lady opts for pieces from J. Crew and Ralph Lauren for her off-duty-wardrobe, she took a different direction yesterday with her $695 Western-inspired shirt. The flattering blouse's deep red hue screams fall and is quite a departure from the gingham-print blouses she's often seen wearing.

The first lady has been seen in several casual ensembles the past couple of weeks. While visiting the victims of Hurricane Harvey, she wore khaki pants, a chambray button-down shirt and some Converse sneakers. She also sported a pair of mirrored sunglasses, a slight departure from her usual tortoiseshell frames, and a hat with "TEXAS" in white lettering on the front.

Just several days before, she stepped out in a similar outfit -- a crisp white button-down shirt, black trousers that hit just above her ankles and a pair of white Stan Smith sneakers from Adidas.

Following their return from Camp David, the first couple marked the 16th anniversary of the September 11 attacks with a moment of silence at the White House on Monday morning.

The first lady donned an appropriate outfit for the somber occasion, wearing a head-to-toe black ensemble. Melania wrapped up in a black belted jacquard Michael Kors coat for the event that was held on the White House's South Lawn.
