Kristin Cavallari will no doubt sail through her maternity months in a haze of chic billowing chiffon, and hip printed smocks.
But today the 25-year-old made the most of her still slender frame to showcase one of this season's trickiest trends - the high-waisted flare.
The Hills alum is aware that her time for fitted clothes will soon be up, and has already started preparing for her bump by using coco butter - which will help her avoid getting stretch marks as her baby grows.

She tweeted today: 'I've already started my coco butter routine. Pregnant ladies u know what I'm talking about ;)'
Kristin also tweeted LA steak restaurant STK to thank them for their food last night, suggesting she is determined to up her iron intake, too.
It's all working as Kristin looked lovely in her pair of flared denims, matched perfectly with a floral blouse for her trip to upscale shopping mall, The Grove.
The expectant mother was joined by her attentive fiance, Jay Cutler, 38 , who kept an eye on his beloved's step as she negotiated the cobbles.
The couple were though to have separated until Jay was spotted cheering is support for Kristen at Dancing with the Stars.

And earlier this week, her beau took to Twitter to thank fans, and to set the record straight.
He posted: 'Thanks for all the tweets. We couldn't be more excited. We don't usually comment on our relationship but for the record I never broke up with Kristin. Its unfortunate some people are saying hurtful things during such a joyous moment in our life.'
A source tells Us Weekly that the former Hills star is thrilled about becoming a mother.
'She is really happy. She is in the early stages, but she can't wait to be a mom,' an insider told Us Weekly.

Despite the apparent rough period in her relationship with the NFL player, which saw Jay briefly breaking off their engagement if not their relationship, friends say that the couple are a match made in heaven.
'(Jay) absolutely adores her, he worships the ground she walks on and she is so in love with him,' the source added.
'This is a real match, they are made for one another. Everyone is so happy that they are going to have a baby together. She's going to be a great mom.'
Apparently the couple have known about the pregnancy for some weeks but have kept it under wraps.
According to People magazine the couple said: ‘We are thrilled to announce we are expecting our first child together. It's an amazing time in our life and we can't wait to meet the new addition to our growing family.’
A source close to the couple confirmed the news to MailOnline.
The betrothed couple made their first public outing since getting back together at Friday night's Cirque Du Soleil show in Santa Monica.
Kristin looked stunning in a knee-length sequin embellished dress which boasted sheer paneling around the neckline.
While the happy couple posed up together on the red carpet the Chicago Bears star was also seen stepping back, letting his lady take the limelight.
The former reality star appeared to enjoy the performance and tweeted: ‘Ovo was amazing!!! The performances were insane!!’
The couple's first public outing together comes after the couple reunited last month.

Kristin confirmed her engagement to Cutler was back on in December and was said to be delighted.
The sports star first proposed in April 2011 and Kristin had busied herself planning for a summer 2012 wedding.
But the couple put the wedding on ice shortly after their engagement party in July last year before getting back together.
While the bride-to-be looks happy and carefree, Kristin has endured a rough time of late after her father, Dennis Cavallari, was accused of having a five-year relationship with a woman who is not his wife.
Orange County resident Tracy Sills claims she enjoyed a long term relationship with Kristin’s father but ended the relationship when she learned he was married.
