Hailey Bieber's 18 best pregnancy style moments

Posting to her Instagram story, Hailey proved that even with a bump, you can never go wrong with a red mini dress and a pair of butter-yellow pointed-toe pumps.

For holiday date night Hailey decided on a lemon yellow toned sheer strapless dress from Jacquemus, a pair of white framed sunglasses and a set of pointed-toe kitten heels.

Hailey's husband Justin shared a cute snap of the two whilst on holiday just a few days ago. Hailey opted for a bold yellow crochet polo top with a contrasting green collar. She paired the statement shirt with a Ralph Lauren Polo cap in the same green hue as the accenting collar and a set of comfortable yellow striped mini shorts.

In a look that screamed 'classic Hailey Bieber' she wore a simple jeans and a white tee, with a black blazer with statement shoulders. A buttery yellow tote bag finished off her elevated 'lewk'.

Giving major wholesome vibes, Hailey shared an Instagram post wearing some classic dungarees which she'd rolled below her bump. She paired them with a simple white tee and the cutest red hat which drew out the rosy blush on her cheeks.

Embracing the sporty-fuelled micro trends of the moment, she wore a navy Fila shirt paired with some short shorts. Is this a sign that Fila will be making a New Balance-esque resurgence? 

This is a classic Hailey Bieber silhouette, proving that she's not changing her style for pregnancy, and is working with her bump, not around it. 

She oozed cool in Laqun Smith and Magda Butrym at an event for Rhode wearing a skintight dress and mega boxy, oversized blazer. 

Hailey's ivory asymmetrical dress she wore for a night out in New York in June draped elegantly over the body, creating a sophisticated silk clad silhouette. The high collar and short sleeves added a touch of modesty, while the loose fit accommodated her baby bump perfectly.

Is there anything more classic than the nautical stripe? Giving the classic style a girly edge, Hailey wore a two-tone pink stripey top, simply paired with black floaty trousers and black accessories.

In a look that gives major 'rich mom' vibes, Hailey wore a yellow and black rugby-striped style jersey slung over her shoulders. She elevated her long-sleeved top and jersey low-rise trouser combo with a BMW cap, a YSL Hobo bag and an iced coffee.

Perfectly combining It-girl chic and business casual, Hailey wore a cream strapless top paired with pleated wide-leg trousers from the same colour palette. She finished off with a tan Hermès Kelly and of course, her trusty diamond 'B' necklace.

Keeping this casual, Hailey chose to sport a semi-sheer knitted longsleeve under a leather blazer. She paired it with her favourite blue jeans and her diamond-encrusted 'B' bubble necklace.

While on holiday with her husband Justin Bieber, Hailey decided to keep things seriously chic, donning a pair of blue jeans with a statement leather belt, a pair of square-toed loafers and an elegant balloon-sleeved blouse, perfectly buttoned to show off her bump.

Lounging with a healthy smoothie, Hailey sported a comfy white tee and denim shorts, baring her bump. The ensemble was elevated by her whopper engagement ring and retro baseball cap, making it clear that even in casual settings, her style is always on point.

In an embellished pink butterfly halter top and loose jeans, Hailey embraced her bump with a Y2K edge. The 1990s style top added a dose of cool-girl, rewriting the rules of maternity wear. Her loose hair and glowing makeup completed the look.

Rocking a red Fila cap and denim dungarees, Hailey is nailing the laid-back, mum-to-be style agenda. Proving that maternity fashion can be both practical and stylish, the casual black T-shirt and minimal makeup highlighted her natural beauty.
