That's a sheer risk! Hilary Duff braves the chill in see-through top while shopping for New Year's Eve outfit

She has shed all of her baby weight so Hilary Duff has every reason to show off her fantastic figure.
The new mother must have been looking forward to her first New Year's Eve celebration since giving birth in March when she stepped out on Monday to do some solo shopping for the perfect party dress.
The chilly 50-degree Fahreinheit weather, however, may have been too much for Hilary, whose purple down jacket was totally unzipped.

It's a bit chilly: Hilary Duff grimaces against the cold, while flashing her bra underneath her thin black top during a solo shopping trip on New Year's Eve

Hilary's sexy see-through black turtleneck was totally exposed and showing the outlines of her bra underneath.
The thin knit fabric was not enough to keep out the cold and Hilary grimaced for a moment.
The 25-year-old actress matched her casual top with skinny jeans, rubber-heeled trainers with chocolate-brown laces and dark shades.
She'd just raided Saks Fifth Avenue and another store in Los Angeles for some last minute accoutrements to the outfit she no doubt intended to wear for a New Year's Eve celebration.

Getting ready: Hilary, who was loaded down with purchases, was in search of the perfect outfit to wear on New Year's Eve and it looks like she found it

Hilary had her hands full carrying two large shopping bags, but wore her favourite black Chanel shoulder bag with the chain link strap across her middle.
The former Lizzie McGuire star spent Sunday afternoon stocking up on groceries for New Year's with her adorable nine-month-old son, Luca.
Hilary was spotted in the parking lot, looking like a woman with a mission while pushing the trolley with Luca in the blanketed seat and her large handbag in the basket.

Mommy and me: Hilary took her nine-month-old son Luca with her on a run to Ralphs supermarket on Sunday

Coffee break: Hilary also stopped by her local Starbucks on Sunday for a couple hot brews, for her and presumably her husband Mike Comrie

She also fit in her usual run to Starbucks, emerging with a tray filled with two steaming cups of coffee.
Wearing red skinny jeans, a grey jumper and woolly grey scarf, and minimal make-up, Hilary looked blissfully happy to get outdoors following an evening of rainfall.
Little Luca, who happily relaxed with his blue pacifier, wore a cute grey hooded jumper that seemed to resemble his mother's outfit.

So happy: Hilary, pictured with her husband at a March of Dimes event in December, tweeted, 'I'm just thinking about my year and feeling so blessed for my precious boy & Mike!'

The What Dreams Are Made Of singer is the happiest she's ever been, thanks to her husband of two years, Mike Comrie and their baby boy.
And she's had a wonderful time turning the colonial-style Beverly Hills mansion she bought in the summer of 2010 into a home.
Hilary shared her gratitude with friends and fans on Saturday by tweeting: 'Having a child is so special! I know it's not NYE yet but I'm just thinking about my year and feeling so blessed for my precious boy &Mike!'
