Brigitte, 64, stepped out in a sleeveless navy mini dress for the visit to Euxinograd Palace.
The dress came several inches above the French first lady’s knee, showing off plenty of leg.
But other than the risqué hemline, Brigitte’s choice was quite conservative, and hung loosely about her body.
A high neckline was topped off by an unusual black, green, and blue sequin ruffle across her bust.
The dress she chose today was similar to the one she showed off yesterday, as both were relatively plain navy mini dresses.
However yesterday’s dress was much more fitted to Brigitte’s body, and she paired it with a handbag and matching jacket.
Unlike yesterday, Brigitte chose to forego a jacket, revealing her bare arms to the sun.
She did, however, wear a pair of American tan tights as she usually does when wearing a mini dress.
Completing the look was a pair of black suede court shoes and minimal jewellery.
Brigitte opted not to carry a handbag or wear any sunglasses despite the bright sunny weather.
Her hair was freshly blow-dried, and she wore it in a stylish bob about her shoulders.
The French politician’s wife kept her make-up minimal, opting for lashings of mascara and a bronzed colour on her cheeks but not much else.
Earlier this week, Brigitte wore a sexy red zip-through dress as she arrived in Salzburg.
It featured a zip up front and a zip on the right breast, as well as a biker-jacket-like fastening on the collar.
Brigitte accessorised with a small black satchel and black pointed stiletto heels.
Her hair was perfectly coiffed as usual and a pair of thick black sunglasses finished off the look.
