The former Lizzie McGuire actress treated the pavement as a catwalk, teetering along in sky-high heels while popping to a florist to pick up a bunch of red peonies.
While most opt for jeans and boots while trekking around town, Hilary slipped her pins into skin-tight leather leggings.
She warded off the mild LA chills with a green and black checked jumper, before finishing her look with cream courts which featured eye-catching metallic toe caps.
Jewellery-wise she kept things simple with a gold pendant necklace and a chunky boyfriend watch, plus her blindingly huge wedding sparkler, of course!
But it's not just her chic off-duty outfit we're loving - the starlet looked totally immaculate in the beauty department too.
Her blonde locks were tonged into loose boho waves, and she flaunted mega-fluttery lashes with pretty petal pink lips.
